Efficient Characterization of Coherent and Correlated Low-Degree Noise in Layers of Gates
Marianna Crupi, J. Ignacio Cirac, Flavio Baccari
We present a quantum process-tomography protocol based on a low-degree ansatz for the quantum channel, i.e. when it can be expressed as a fixed-degree polynomial in terms of Pauli…
