Abstract

Noise drift in quantum hardware is an important obstacle for scalable quantum computation, e.g. when performing complex quantum algorithms with runtimes exeeding the characteristic time of the noise drift. I address this problem by proposing drift-adaptive quantum error correction, and prove metrological bounds in its operation fidelity.
