Qubit noise deconvolution

Abstract We present a noise deconvolution technique to remove wide class of noises when performing arbitrary measurements on qubit systems. In particular, we derive the inverse map most common single noisy channels, and exploit it at data processing step obtain noise-free estimates observables evaluated system subject known noise. illustrate self-consistency check ensure that characterization is accurate providing simulation results for generic Pauli channel, as well experimental evidence decoherence occurring Rigetti quantum hardware.
