NewsQuantum PhysicsPhysicists are mostly unconvinced by Microsofts new topological quantum chipThe evidence for Majorana qubits didnt win over many skeptics at the Global Physics Summit Microsofts topological quantum chip, the Majorana 1 (pictured), could be a boon to quantum computing, but some physicists are skeptical that the chip does whats claimed.MicrosoftBy Emily Conover8 seconds agoANAHEIM, CALIF. At the worlds largest gathering of physicists, a talk about Microsofts claimed new type of quantum computing chip was perhaps the main attraction.Microsofts February announcement of a chip containing the first topological quantum bits, or qubits, has ignited heated blowback in the physics community. The discovery was announced by press release, without publicly shared data backing it up. Aconcurrent paper inNaturefell short of demonstrating a topological qubit. Microsoft researcher Chetan Nayak, a coauthor on that paper, promisedto provide solid evidence during his March 18 talkat the American Physical Societys Global Physics Summit.
