Microsoft improves qubit lifetime from 10 ms to 20 seconds

Microsoft has reported improved materials in its topological qubit system. In the new device the company replaced aluminum with lead in the superconducting layer and changed the semiconductor structure, which increased the lifetime of the parity state from less than 10 ms to more than 20 seconds, Ars Technica writes. Separately, Atom Computing announced progress in error correction on neutral atoms. […]
