General characterization of qubit-preserving impairments on two-qubit Bell nonlocality
R. A. Brewster, Gerald Baumgartner, Yanne K. Chembo · Physical Review A · 2023
A general technique for experimentally characterizing the effect of qubit-preserving impairments on the Clauser-Horne-Shimony-Holt parameter is introduced. This technique is independent of the underlying qubit encoding and is theoretically demonstrated for specific example impairments in polarization-encoded quantum-optical qubits. Included in this analysis is how spectrotemporal impairments can be incorporated into this technique.
