CNOTDihedralRBFitter

class CNOTDihedralRBFitter(cnotdihedral_Z_result, cnotdihedral_X_result, elmnts_lengths, rb_pattern=None)

Bases: qiskit.ignis.verification.randomized_benchmarking.fitters.RBFitterBase

Class for fitters for non-Clifford CNOT-Dihedral RB.

Derived from RBFitterBase class. Contains two RBFitter objects.

Parameters

• cnotdihedral_Z_result (qiskit.Result) – list of results of the RB sequence that measures the ground state.

• cnotdihedral_X_result (qiskit.Result) – list of results of the RB sequence that measures the \(|+...+>\) state.

• elmnts_lengths (list) – the group elements lengths, 2D list i x j where i is the number of patterns, j is the number of elements lengths.

• rb_pattern (list) – the pattern for the RB sequences.

Methods

add_data	Add a new result.
calc_data	Retrieve probabilities of success from execution results.
calc_statistics	Extract averages and std dev.
fit_data	Fit the non-Clifford cnot-dihedral RB results.
fit_data_pattern	Fit the RB results of a particular pattern to an exponential curve.
plot_rb_data	Plot non-Clifford cnot-dihedral randomized benchmarking data of a single pattern.
