InterleavedRBFitter

class InterleavedRBFitter(original_result, interleaved_result, cliff_lengths, rb_pattern=None)

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

Class for fitters for interleaved RB, derived from RBFitterBase class.

Contains two RBFitter objects: the original RBFitter and the interleaved RBFitter.

Parameters

• original_result (list) – list of results of the original RB sequence (qiskit.Result).

• interleaved_result (list) – list of results of the interleaved RB sequence (qiskit.Result).

• cliff_lengths (list) – the Clifford lengths, 2D list i x j where i is the number of patterns, j is the number of cliffords 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 interleaved RB results.
fit_data_pattern	Fit the RB results of a particular pattern to an exponential curve.
plot_rb_data	Plot interleaved randomized benchmarking data of a single pattern.
