Google gets an error-corrected quantum bit to be stable for an hour
(In addition to a standard surface code, Google includes a few qubits that handle a phenomenon called “leakage,” where a qubit ends up in a higher-energy state, instead of the two low-energy states defined as zero and one.) The key result is that going from a distance of three to a distance of five more […]
