iqm.benchmarks.compressive_gst.mgst.reporting.reporting.dephasing_probabilities_2q(X_opt_pp: ndarray, X_ideal_pp: ndarray) → list[ndarray]

Determines the local dephasing channel parameters which best describe the noise model.

Works for two qubit gates only

Parameters:

• X_opt_pp (ndarray) – Array where reconstructed CPT superoperators in Pauli basis are stacked along the first axis.

• X_ideal_pp (ndarray) – Array where target gate CPT superoperators in Pauli basis are stacked along the first axis.

Returns:

The two best fit dephasing probabilities

Return type:

list[ndarray]
