Improving qubit coherence using closed-loop feedback

Improving qubit coherence using closed-loop feedback

The presence of various noises in the qubit environment is a major limitation on qubit coherence time. Here, the authors demonstrate the use a closed-loop feedback to stabilize frequency noise in a flux-tunable superconducting qubit and suggest this as a scalable approach applicable to other types o...
