The dynamics of a quantum sensor (IMAGE) ETH Zurich Department of Physics Caption Errors such as noise cause a damping of the signal relative to the ideal case. Finite-rate quantum error correction can recover substantial parts of the lost signal strength, but also shifts the sensing frequency, leading to the progressive build-up of a bias (shown as grey bars).
