Irish startup Equal1 has unveiled the worlds first quantum computer that runs on a hybrid quantum-classical silicon chip.Dubbed Bell-1 after quantum physicist John Stewart Bell the computer weighs around 200kg and plugs into a regular electrical socket. The rack-mountable machine is designed to simply slot into high-performance computing (HPC) data centres alongside standard servers.Equal1s CEO Jason Lynch told TNW that combining quantum technology with todays most advanced classical processors offers the fastest route to a quantum computer capable of potentially world-changing calculations.The potential applications are endless. Quantum computers have the potential to solve complex problems that classical computers cannot, which could lead to breakthroughs in drug discovery, cryptography, modelling, and AI.The of EU techThe latest rumblings from the EU tech scene, a story from our wise ol' founder Boris, and some questionable AI art.

This is the best way to scale quantum computing at the pace required.The Bell-1 quantum computer inside its shield. Credit: Equal1Equal1 marries classical transistors (for normal computing tasks) and quantum transistors (for qubits) in a single silicon-based chip. Qubits, akin to bits in a regular PC, are the basic units of information in a quantum computer. The more you have, the faster the machine.Most quantum computing technologies are based on either trapped-ion or superconducting qubits. However, Equal1s design uses silicon-spin qubits.Bell-1 is noticeably smaller than most quantum computers out there. The company credits this to its closed cycle cryo-cooler that allows the machine to operate at 0.3 Kelvin (-272.85C) without requiring massive external dilution refrigerators.Most quantum computers need to be kept super cool because heat causes errors by disrupting the delicate quantum states of qubits (there are exceptions, however).The machines cooling system.

However, Googles machine isnt available to buy Bell-1 is.Tech companies are recruiting more and more quantum experts now as they explore the future possibilities of this technology, said Lynch. Bell-1 will help them, and others, run experiments like quantum phase estimation and error correction that will form the foundation for more powerful processors in the future.The chip for Bell-1.

The startup currently employs about 45 people and, while still based in the Irish capital, has an expanding presence in the Netherlands one of the world leaders in quantum technology.The Netherlands Organisation for Applied Scientific Research (TNO) recently backed Equal1 with an undisclosed investment. Last year, the Irish company opened a research facility close to TU/Delft, an emerging hub for quantum tech startups such as QuantWare.By leveraging standard semiconductor manufacturing, Equal1 aims to bring quantum computing closer to real-world applications faster than its competitors. That competition pool is growing, though, and fast. In the past few months alone, Google launched quantum chip Willow, Microsoft unveiled Majorana, and Amazon revealed Ocelot.Quantum computing is on the new agenda for TNW Conference, which takes place on June 19-20 in Amsterdam.
