Quantum startup demos spin qubits fabbed with existing tech

Quantum Motion demo based on 300mm wafers, targeting feasible 'fault tolerant' quantum computers

Startup Quantum Motion is joining the silicon spin qubit gang with its own technology that can fit thousands of quantum dots onto a single silicon chip fabricated in a commercial semiconductor foundry. The move marks another small step along the road to building full-scale fault-tolerant quantum systems.…
