A dual-rail cavity qubit flags errors during logical measurements

Jul 6, 2023

Kevin Chou and colleagues encode a qubit in two superconducting cavities and demonstrate a logical measurement that detects erasures. They characterize storage errors, testing a building block for future error-correcting codes.

Why it matters

Detecting the location of photon-loss errors could simplify correction when many such qubits are combined into a larger code.
