Self-consistent tomography of temporally correlated errors

Abstract The error model of a quantum computer is essential for optimizing algorithms to minimize the impact errors using correction or mitigation. Noise with temporal correlations, e.g. low-frequency noise and context-dependent noise, common in computation devices sometimes even significant. However, conventional tomography methods have not been developed obtaining an describing correlations. In this paper, we propose self-consistent protocols obtain temporally correlated errors, demonstrate that our are efficient noise.
