Query: Spectral Transfer Tensor Method for Non-Markovian Noise Characterization   With continuing improvements on the quality of fabricated quantum devices, it
becomes increasingly crucial to analyze noisy quantum process in greater
details such as characterizing the non-Markovianity in a quantitative manner.
In this work, we propose an experimental protocol, termed Spectral Transfer
Tensor Maps (SpecTTM), to accurately predict the RHP non-Markovian measure of
any Pauli channels without state-preparation and measurement (SPAM) errors. In
fact, for Pauli channels, SpecTTM even allows the reconstruction of
highly-precised noise power spectrum for qubits. At last, we also discuss how
SpecTTM can be useful to approximately characterize non-Markovianity of
non-Pauli channels via Pauli twirling in an optimal basis.
