Water is a precious resource, making up over 60% of the overall body mass of humans, and a sustaining source for most life. With the ability to cut rock, melt salt, and boil, it is the signature substance of Earth, our little blue dot. As it is a finite resource as well, and becoming more scarce, small ways to save those lifegiving drops are necessary and welcome. Enter the RAINDROP by Junwoo Lim, a planter + umbrella stand that captures the remnant drops left over from a wet umbrella to water a plant below. With graceful form, just as appropriate in a gallery as a home, let the RAINDROP save your floors and feed your plants, all at once.Designer Junwoo Lim is on a mission to help people participate in sustainability, no matter their personal feelings on the subject. People who care about these issues will sometimes use reusable water bottles, or reducing single use plastics requires that you are aware of the problem and how to take steps to solve it. With RAINDROP, everyone who uses an umbrella participates, passively but just as effectively. This presents a creative way to go about solving for sustainability, and promoting everyone to participate in actions good for the earth, not just those that happen to be aware.Utilizing the Unexpected Red theory, where a pop of red can really elevate a space, this matte red finish provides refreshing contrast to the greenery growing inside, as well as form language on top that almost looks like the blooming of a tree itself.RAINDROP would fit perfectly in a public space or community center, possibly starting conversations about sustainability with those that might not be informed. The plants and humans both benefit from these types of discussions, studies showing that the way we speak around plants effects their overall health and well-being. Happy to be thought of, and happy to be watered, the RAINDROP makes it easy to be kind to our leafy friends.For more information on RAINDROP by Junwoo Lim, please email the designer at studio.limjunu@gmail.com.

Its not a complicated process: You form blocks of compressed seedling mix, lay them out on a tray, then plant into them. It works much like growing seeds in a plastic seed tray, without the tray. Using less plastic is only one benefitthe real reason people love soil blocking is that it creates seedlings with incredibly strong root systems, without getting root-bound. The air around the block acts as a pruning mechanism; the roots grow to the edge of the soil and then stop. The roots hold the soil block together, and can be easily up potted to continue growing inside, or transplanted directly into the garden.The drawbacks to soil blockingIn order to make seed blocks, you need soil that will compress well and hold together, and most often, that involves peat. Peat, a byproduct of swamps and bogs, is controversial because the harvesting has a dramatic environmental impact. Some people have had success with other mediums like coconut coir, but those people do not include me. Ive tried coconut coir a few years in a row and have suffered from lack of germination and blocks falling apart, so I have gone back to seedling mixes with peat.The other major drawback to soil blocking is the actual blocking: Its a pain in the ass. My first year, I was inspired by one of my gardening mentors, Meg Cowden of Seed to Fork, who speaks of the calm and meditative nature of blocking. Now, I regard blocking as a necessary evil each year that takes a lot of energy and soil. Still, the results speak for themselves.Soil blocks perform exceptionally well in tests against seed trays. Step one: Get a soil blocker Credit: Amanda Blum The first thing youll need is a soil blocker. There are all kinds of blockers on the market now, and many are inexpensive. Soil blocking is similar to making a sand castle or snow castle: You pack the soil tightly into a cube; the soil blocker compresses the cube, and helps spit it out. Soil blockers come in different sizes and layouts. There are mini blocks, which are an inch or so large (for flowers), and maxi blocks, which are four by four inches. But most people are going to want to start with two-by-two-inch blocks. A basic blocker will spit out four of these blocks at once.Step two: the right seed mix, at the right moisture level Credit: Amanda Blum Next, youll need the soil. Different kinds of plants at different stages all need different soil. When starting seeds, you want seedling mix, which is devoid of nutrients, has a lot of moisture retention, and is made of fine particles, so it can compact into seed trays. This is perfect for seed blocking, as long as that mix also includes peat or coconut coir. Get more soil than you think youll need, since by compressing the soil to make the block, you use more soil than you might with seed trays. I was able to make 100 blocks from a 12-quart bag. Empty the bag into a bin or other watertight container, and mix it with water. You want to use roughly three times the amount of water as soil, adding it slowly, and stopping to mix the water in two to three times. Soil can absorb an absurd amount of water; you want the soil wet, but not sopping. Grab a handful of the mix, and squeeze it in your hand. Does it clump together? If so, youve got enough water. If not, add more until it does. Step three: Have a tray for the soil blocksThe blocks will live on a tray, and it doesnt matter much what kind of tray, as long as it can hold an inch or so of water, and is watertight. If you were using seed trays, they'd still need something to sit on like a bottom tray, so you've likely got some around. Ive seen setups with standard 1020 trays and setups with cafeteria trays. The blocks sit right next to one another, so a 1020 tray can hold 50 blocks. A cafeteria tray, depending on its size, can hold much more.Step four: Set up your dibbles On the left, interchangeable dibbles, and on the right, dibbles installed on the blocker. Credit: Amanda Blum Before we start making blocks, you want to set up your dibbles. When you plant seeds, you have to plant them at the right depth, depending on the kind of seed. Sunflower seeds are buried very deep, for instance, while carrot seeds sit close to the surface of the soil. Your seed blocker has different dibbles you can add to your blocker, and theyll make corresponding indentations in the soil block, so you can insert a seed more easily.Step five: Start blocking Credit: Amanda Blum Now lets get down to actual blocking. Again, if youve ever made a sand castle, this wont seem foreign, but the technique requires a little finesse. Holding the blocker upright, push it into the seedling mix over and over, rocking it back and forth, until you hit the bottom of the bin. This pushes soil into the blocker. Swiveling the blocker left and right while pressing against the bottom of the bin compresses the soil. After a few passes, lift the blocker upside down, and check that the four chambers are full. If they're not, keep taking passes, or you can just keep the blocker upside down and pack soil in with your other hand.Step 6: Line up the blocks on the tray Credit: Amanda Blum To dispense the blocks, move to the tray that will hold them. Push the blocker against the tray, while slowly depressing the handle and lifting up. This process should product four perfect blocks, but that doesnt always happen, and if a block looks like it will fall apart, pick it up and toss it back into the bin. Its just soil; it will crumble apart. The blocks are delicate at this stage but not immovable, if youre gentle. Credit: Amanda Blum Now, start all over, and dispense more blocks. Keep going until you have as many as youd like on that particular tray. At this point, its time to plant some seeds. Treat each block like a cell in a seed tray. Plant one or two tomato seeds, or a bunch of carrot seeds, or a single pumpkin seed. Cover the seed up with some extra seed mix.Step 7: Seed the blocksFrom here on it, the process is just like growing in seed trays. The soil needs heat, so place your tray on a heated seed mat. The blocks need water, so you should fill the tray every few days with just enough water to cover the bottom of the tray entirely. The blocks will soak up the water and remain moist, ensuring germination. The seeds need humidity, so covering the blocks with a plastic dome will ensure theres enough moisture. Finally, the blocks need light, so ensure theres enough light on the tray, especially after the seeds germinate. Tomatoes grown in seed blocks Credit: Amanda Blum The seeds will grow just as they would in a seed tray scenario, and at some point, will be too big for the blocks. Along the way youll want to choose one seedling per block, and cut the other seedling away. You can choose to up-pot the blocks into containers or paper pots, or plant the blocks right in the garden, if it's not too early. Usually I up-pot the seedlings after a few weeks, and theyll remain in four-by-four-inch pots until it's time for them to go in the ground.Blocks that dont germinate for some reason can be recycled for next year by simply tossing the block back into the bin of seedling mix.

It finally happened: Threads officially allows you to choose a default feed to see when you open the app, whether that be "Following" or a custom feed you've created yourself. This means that when you open Threads, you'll be able to view posts from the accounts you chose to follow, instead of seeing what the algorithm wants you to. Meta has been testing this feature for a few months, and is now rolling it out to everyonein addition to a few other new features.How to change Threads' default feed to FollowingThe process of changing your default feed is straightforward. Follow these steps:Open the Threads app on your phone and go to the Home tab.You'll see all your feeds in different tabs at the top of the screen, just below the Threads logo. Tap and hold any of these feeds and select Edit Feeds.This will reveal all your feeds in a list. Hold any feed here and drag it up or down to reorder the list. The first one in the list will automatically become your new default feed.Feel free to set it to Following or any custom feed you've created. Note that this feature is being rolled out slowly, so it may take a while before you see it on your phone.Other updates to ThreadsWith the same update, Threads has added a few more useful features to the app. My personal favorite is the new video player, which finally has basic playback controls and a progress bar that you can easily access. There's a new play/pause button in between the rewind and forward buttons. You can use those buttons to skip back or forward by 10 seconds at a time. The progress bar appears below each video and it's big enough to scrub through videos. It's a great change: Without these features, watching videos on Threads often felt like watching looping gifs. You can also limit replies and quotes of your posts. When you compose a new post in Threads, tap the Anyone can reply & quote button, located to the left of the Post button. This lets you limit replies and quoting to your followers, mentioned accounts, or accounts you follow.Separately, Meta is testing the ability to add up to 10 topics to your Threads profile. Tapping these topics leads you to conversations around those subjects, similar to how hashtags work on other social media platforms. When you compose a new post in Threads, you may see a button that lets you add a trending topic to the post. If you use it, your post could reach a larger audience than usual.

AMD is seriously outgunning Nvidia, restocking way more RX 9070 GPUs compared to RTX 5000 models, a fresh rumor insists.

A new leak claims that the rumored AMD "Sound Wave" APU will have similar performance to Qualcomm's Snapdragon line

It's been a painful year so far for megacap technology giants and 2025 is only getting started.

Severance is a set design wonderland. From a massive mirrored corporate monolith in New Jersey to a classical train station in upstate New York, the shows distinctive visual languagewhich has captivated audiences and critics alikerelies on actual places that have been carefully chosen to mess with your head. These arent just random pretty buildings. Theyre psychological weapons that connect the dots in the same way the writers weave the tapestry of the tale. Severance follows a group of humans that go through a procedure to separate their (outie) real lives from their (innie) corporate bees working for a mysterious industrial conglomerate call Lumon, effectively turning four people (Mark, Helly, Irving, and Dylan) into eight, each with distinct personalities and circumstances. In the same way, the show divides its architecture, confronting an inner corporate hellscape to an outside world that, in its own way, is also its own hellscape.In its second season, Severance has expanded way beyond the creepy white corridors in the severed underground floor of Lumon Industriess of the first season. The show ventures into a more diverse architectural playground that deepens its exploration of corporate control and our fractured modern psyche. The shows filming locations now span from New Jersey to upstate New York to Newfoundland, each chosen not just because they look cool on camera, but because of the subliminal messages their architectural features convey.[Image: Apple TV+]The Lumon headquartersThe most iconic location in Severance is Lumon Industriess headquartersa massive, imposing structure that looms over the landscape like some corporate Death Star. In reality, this architectural marvel is the Bell Labs Holmdel Complex (now known as Bell Works) in New Jersey, a building whose real-world significance perfectly aligns with its fictional role.[Image: Apple TV+]All those companies in the 50s and 60s, they had so much style, they had the most beautiful spaces, and they were proud of what they were doing, explains Jeremy Hindle, Severances production designer, in an interview with Variety. These corporate spaces are designed to dominate you and make sure that you know the rules. No kidding. Thats exactly what makes Severance so viscerally disturbingand so visually compelling. The architecture isnt just pretty. Its predatory.[Photo: Lee Beaumont/Flickr]Designed by renowned architect Eero Saarinen in 1958 and completed in the early 1960s, the Bell Labs complex stands as one of the most significant examples of mid-century corporate modernism in America. Its vast mirrored glass faade earned it the nickname The Worlds Largest Mirror in architectural circlesa fitting metaphor for a show about reflection and duality. The building spans 2 million square feet with a central open-atrium scheme extending a quarter-mile.ca. 1987 [Photo: Gerard Garcia/Getty Images]When Saarinen designed the complex for Bell Telephone/AT&T researchers, it was conceived as a utopian workplace meant to foster community and collaboration. The central atrium was designed to encourage chance encounters between researchers from different departmentsa physical manifestation of the cross-pollination of ideas, a concept that has been reproduced in many other corporate buildings, like Pixars and, most recently, Legos new HQs.Bell Works, ca. 2022. [Photo: Curlyrnd/Wiki Commons]Yet in Severance, this same architecture becomes oppressive and isolating. The cinematography transforms Saarinens idealistic vision into something cold and menacinga very literal visual metaphor of how corporate utopias often become dystopias in practice. As architectural historian Jon Gertner told Curbed, Bell Labs was an idea factory but, in Severance, it became a factory for something far more sinister: the manufacturing of compliant workers through the literal division of consciousness.In Season 2, aerial shots reveal the buildings distinctive shape, which from above resembles a giant goats eyea visual connection to the shows recurring goat imagery and themes of surveillance. The water tower stands as a sentinel, further emphasizing the companys technological dominance over the landscape and its employees lives. Its like the Eye of Sauron, but for corporate America.[Image: Apple TV+]While Bell Works provides the exterior shots, the labyrinthine white hallways of Lumons severed floor were constructed at York Studios in the Bronx. These stark, minimalist corridorswith their fluorescent lighting, white walls, and complete absence of windowscreate a timeless, placeless quality that reinforces the severed employees disconnection from the outside world. Season 2s opening sequence features Mark running through these disorienting corridors, a scene that required weeks of planning and several days to shoot using a high-speed robotic camera called the Bolt. The design deliberately disorients viewers, making it impossible to create a coherent mental map of the spacemirroring the fragmented consciousness of the severed workers themselves. Its architectural gaslighting at its finest.[Image: Apple TV+]This season we also got to see the surreal Mammalians Nurturable Room, where they have the goats. The production team built an enclosed tent on Brooklyns Marine Park Golf Course, with Industrial Light & Magic rendering the walls and ceiling in CGI. This hybrid of physical and digital architecture creates a dreamlike space that exists somewhere between reality and fantasymuch like the severed state itself. The blending of real and virtual elements mirrors the shows exploration of how memory and perception shape our experience of space.The Great Doors factorySeason 2 introduces another corporate space: the Great Doors factory. Its the opposite of Lumon HQs, but no less oppressive. This is where Dylanone of the four protagonistslooks for a new job after being fired from Lumon. He gets interviewed but not hired because he had the severance procedure to split his brains consciousness. Fun fact: Severances creator Dan Erickson was actually working in a door factory when he came up with the idea for the TV series.[Image: Apple TV+]The real location is the Red Owl Collective in the Midtown Arts District, in Kingston, a city in upstate New York. This 10,000-square-foot antique, vintage, and design emporium provides a richly textured industrial backdrop that contrasts with Lumons sterile environment while still conveying themes of labor and production.[Image: Google Maps]What makes these corporate spaces so effective in Severance is how they embody what architect Rem Koolhaas has called junkspaceenvironments designed not for human comfort but for corporate efficiency, where workers become interchangeable parts in a machine. The architecture doesnt just house the corporation; it is the corporation made physicala concrete and glass manifestation of power structures that shape human behavior and identity.[Image: Apple TV+]Brick and mortar split personalitiesIf Lumons corporate architecture represents power and control, the residential spaces in Severance show more intimate themes of identity and memory. Marks and Irvings apartments, filmed at the Village Gate Townhouses in Nyack, NY, and in the Waterfront at the Strand in Kingston, NY, respectively, are also featured in this season. Both represent each of their outies mental states: barren despair for Mark, and dark despair for Irving. Season 2 expands the shows exploration of domestic architecture to visually reinforce the psychological state of characters caught between their innie and outie existences, introducing Dylans residence.In the real world, his familiar middle-class residence is at Kings Landing Condominium on Oxford Lane in Middletown, New Jersey. Whats fascinating about this location is the vision we get from above in one of the episodes. Some see a uterus, others Lumons logo upside down. I see both, perhaps an allegory to one of the shows underlying themes: human reproduction.[Image: Apple TV+]The other side of this coin is the Eagans family residence, the owners of Lumon. Its a massive glass structure visible in aerial shots near the Lumon headquarters, controlling it from afar. Home of the Helly E(gan)the outie of innie Helly Ris truly a dream home. The modernist house embodies a cruel irony: the transparency that the Eagans deny their workers, they enjoy for themselves. They can see out while keeping others from seeing in. The architectural juxtaposition between the workers homes and the Eagan residence visually reinforces the shows themes of class division and power imbalance.[Image: Apple TV+]If you are fascinated by this home and want to know where it is, you are not alone. I spent a few hours researching this one and it doesnt seem to exist in the real world. Like other sets in the show, it appears to have been built as a set and enhanced with digital effects. In the architectural apartheid of Severance, buildings always tell us who has power and who doesnt. The Eagans live in a house where they can see everything, while their employees live in spaces where they can only see what the company allows them to see.[Image: Apple TV+]Public spaces between worldsSeason 2 of Severance ventures beyond the corporate and domestic realms to explore a variety of public spaces that serve as transitional zones between different states of being. These liminal spacestrain stations, parks, gatewaysseem to physically embody the shows central concern with boundaries and thresholds, particularly the boundary between severed and unsevered consciousness.One of Season 2s most architecturally significant new locations is Uticas Union Station, featured in Episode 9, titled The After Hours. Built in 1914 and designed by Allen Stem and Alfred Fellheimerthe same architects behind Grand Central Terminalthis classical train station with its impressive marble pillars provides the backdrop for an emotionally charged scene between Burt and Irving. Its a beautiful space, grand architecture that speaks to an era of transition and movement, making it the perfect setting for a pivotal moment for the characters that resonates with the idea of splitting lives like the severing process does. The classical architecture creates a sense of permanence and history that contrasts with the transient nature of the characters meeting.The production spent approximately $2 million filming at this location for just two days in May 2023, adding fake snow to maintain the wintry Season 2 aesthetic. This transformation of a historical space into a fictional moment is a good example of how Severance uses real architecture as raw material for its psychological landscape.The location also had another less obvious connotation. When the scene ends, Irving takes the 2400RR line, a historical scenic line in the Adirondack Railroad, which begins in Oneida County and ends in the Genesee Counties. If you know anything about cults, those two places should certainly ring several bells, points out one redditor in the Severance subreddit. Mormonism was founded in the Genesee Counties. [] The Oneida Community was a strange highly Puritanical yet also free love (deviant sex encouraging, quasi-communist Christian sect that was founded in Oneida County in the latter half of the 20th century. This clearly connects with Lumon Industriess nature, which has an extremely dark background featuring a mythical origin story, a god-like founder, strange sex and corporate rituals, blind obedience, and child abuse, among other niceties.Some of Season 2s most striking settings were filmed at Minnewaska State Park Preserve in New Yorks Shawangunk Mountains. Used for both the Dieter Eagan National Forest in Episode 4 and the haunting Woes Hollow scenes, these locations leverage natural architecturedramatic cliff views and frozen landscapesto create environments that feel simultaneously beautiful and threatening.The Mohonk Testimonial Gateway in New Paltz, NY, returns in Season 2 as the entrance to the Damona Birthing Retreat. Built in 1908 as the formal entrance to the Mohonk Mountain House resort, this historical gatehouse creates a literal threshold between worldsa perfect architectural metaphor for the shows exploration of divided consciousness. In Episode 9, this gateway serves as the access point to Cabin 5, reinforcing its role as a transitional space between different states of being.Downtown Beacon continues to serve as the fictional town of Kier in Season 2, with the Beacon Building on Main Street functioning as the Hall of Records. The repurposing of this real small-town architecture creates a setting that feels simultaneously familiar and slightly off-kiltera visual strategy that reinforces the shows themes of distorted reality.[Image: Apple TV+]Other transitional spaces include a set prop phone booth constructed in front of a closed car repair shop near Kingstons Wurts Street Bridge, and the shed featured in Season 2, Episode 3 Who Is Alive? positioned below Kingstons Rondout Train Trestle. These constructed elements within existing architectural contexts show how the production designs spaces that connect the severed and unsevered worlds.Season 2 also ventures beyond New York state to the Canadian province of Newfoundland and Labrador for the Salts Neck sequences. These locations portray a run-down, former factory town wounded by the closure of a Lumon production plant. The remote, snowy landscapes contribute to the shows atmosphere of isolation while the abandoned industrial architecture serves as a warning about the consequences of corporate abandonmenta ghost town that represents the ultimate symbol of Lumons disposable view of human labor. Which brings me to the ultimate point: Severance itself, its physical worlds, embodies the ultimate innie-outie dichotomy. A show that is both depressing with glimmers of hope, but ultimately depressing again. Every episode, I wonder if our protagonists would triumph against this techno-capitalists sect (Im sorry, but I get Apple vibes all over, and Im guessing its executives are not into the joke) or disappear into the oblivion of forgetfulness in the innies world and the carcass of mortal decay in the outies world. The answer will probably be both.

Quantum computing stocks got pummeled yesterday, with the four most prominent public quantum computing companiesIonQ, Rigetti Computing, Quantum Computing Inc., and D-Wave Quantum Inc.falling anywhere from over 9% to over 18%. The reason? A lot of it may have to do with AI chip giant Nvidia. Again.Stocks crash yesterday on Nvidia quantum newsYesterday was a bit of a bloodbath on the stock market for the four most prominent publicly traded quantum computing companies. Heres a breakdown of how they performed, according to data from Yahoo Finance:IonQ, Inc. (NYSE: IONQ): down 9.27% to $21.14 per shareRigetti Computing, Inc. (Nasdaq RGTI): down 9.24% to $8.99 per shareQuantum Computing Inc. (Nasdaq: QUBT): down 11.71% to $7.39 per shareD-Wave Quantum Inc. (NYSE: QBTS): down 18.02% to $8.69 per shareAll four of these quantum computing stocks tumbled on the day that AI chip giant Nvidia kicked off its two-day Quantum Day event. In a blog post from January 14 announcing Quantum Day, Nvidia said the event brings together leading experts for a comprehensive and balanced perspective on what businesses should expect from quantum computing in the coming decades mapping the path toward useful quantum applications.But thats not all that Nvidia did. Besides bringing quantum experts together, the AI behemoth also announced that it will be launching a new quantum computing research center in Boston.Called the NVIDIA Accelerated Quantum Research Center (NVAQC), the new research lab will help solve quantum computings most challenging problems, ranging from qubit noise to transforming experimental quantum processors into practical devices, the company said in a press release.The NVAQCs location in Boston means it will be near both Harvard University and the Massachusetts Institute of Technology (MIT).Quantum computing will augment AI supercomputers to tackle some of the worlds most important problems, from drug discovery to materials development, Nvidias CEO, Jensen Huang, said. Working with the wider quantum research community to advance CUDA-quantum hybrid computing, the NVIDIA Accelerated Quantum Research Center is where breakthroughs will be made to create large-scale, useful, accelerated quantum supercomputers.Its not the first time stocks reacted to Nvidias CEONvidias announcement of the NVIDIA Accelerated Quantum Research Center apparently sent shivers down the spines of many quantum computing investors, with shares of QBTS, RGTI, IONQ, and QUBT all crashing.Before Nvidias announcement yesterday, IonQ, Rigetti, D-Wave, and Quantum Computing Inc. were the leaders in the nascent field of quantum computing. And while they still are right now (Nvidias quantum research lab hasnt been built yet), the fear is that Nvidia could use its deep pockets to quickly buy its way into a leadership spot in the field. With its $2.9 trillion market cap, the company can easily afford to throw billions of research dollars into quantum computing.As noted by the Motley Fool, the location of the NVIDIA Accelerated Quantum Research Center in Boston will also allow Nvidia to more easily tap into top quantum talent from Harvard and MITtalent that may have otherwise gone to IonQ, Rigetti, D-Wave, and Quantum Computing Inc.Nvidias announcement is a massive about-face from the company in regard to how it views quantum computing. Its also the second time that Nvidia has caused quantum stocks to crash this year. Back in January, shares in prominent quantum computing companies fell after Huang said that practical use of quantum computing was decades away.Those comments were something quantum computing company CEOs like D-Waves Alan Baratz took issue with. Its an egregious error on Mr. Huangs part, Bartaz told Fast Company at the time. Were not decades away from commercial quantum computers. They exist. There are companies that are using our quantum computer today.According to Investors Business Daily, Huang reportedly got the idea for Nvidias Quantum Day event after the blowback to his comments, inviting quantum computing executives to the event to explain why he was incorrect about quantum computing.Quantum Computing Inc. Q4 results may also play a roleBut it wasnt just the Nvidia news that may have contributed to yesterdays quantum sell-off. Also yesterday, Quantum Computing Inc. (QCi) announced its Q4 2024 results.Those results were not good news for the company. As The QuantumInsider noted, QCI announced it had $62,000 in total revenue for the quarterdown from $75,000 in the quarter a year before. Wall Street consensus had expected around $400,000 in revenue. The company also had a net loss of $51.2 million versus a net loss of $6.8 million in the same quarter a year earlier.Announcing its Q4 results, Quantum Computing Inc.s CEO, William McGann, said QCi made meaningful progress in the fourth quarter strengthening our financial position to support the continued advancement of our quantum solutions and foundry services. With a significantly bolstered balance sheet, we are well-positioned to scale operations and accelerate commercialization efforts.He also noted that the company is still on track to launch its foundry that will produce quantum photonic chips in early 2025.Still, that news was not enough to mitigate investor disappointment over its Q4 results. The stock fell over 11% yesterday and is down over 10% in premarket trading today.Quantum stocks sometimes rise and fall in unison, so when one company posts bad results, it can tend to drag the stock prices of other quantum computing companies lower, too.How quantum computing stocks are trading todayAfter the announcements above, including Huang announcing Nvidias intention to launch the NVIDIA Accelerated Quantum Research Center, quantum computing stocks tankedand they arent doing much better today. As of the time of this writing, the four most prominent quantum computing stock prices are all down in premarket trading:IONQ: down 1.09%RGTI: down 3.00%QUBT: down 10.4%QBTS: down 4.83%Since the start of 2025, three of those four quantum computing stocks have been hit hard. As of yesterdays close IONQ had lost more than 49% of its value, RGTI has lost 41%, and QUBT has lost 55%. Only QBTS has seen a modest gain of 3.45% for the year to date, though that gain has been wiped out in premarket trading this morning as of the time of this writing.However, despite these quantum computing stocks being in the red for 2025, over the past 12 months, all have shown impressive returns, with IONQ up over 120%, RGTI over 425%, QUBT over 495%, and QBTS over 323% as of yesterdays close.As for Nvidia, investors seem not to care much about its quantum announcement. Yesterday, NVDA stock closed up just 0.86%, and today, the stock is currently down a paltry 0.76% in premarket trading. Since 2025 began, NVDA stock has been down almost 12%, while it has been up over 31% over the past 12 months, as of yesterdays close.This post has been updated with additional context on QCis earnings.
