Error-corrected quantum qubits glitch about 5 in a million times, a step toward ‘megaquop’ computing

Summary

Science News reports that error correction has produced qubits that glitch only about 5 times in a million, which it calls the first step toward a new phase for quantum computing and the ‘megaquops’ era. Ars Technica reports a demonstration of error-corrected qubits in which errors drop sharply as the qubits grow, going well beyond breakeven.
