RBFitter

class RBFitter(backend_result, cliff_lengths, rb_pattern=None)

Bases: RBFitterBase

Class for fitters for randomized benchmarking.

Parameter

• backend_result (Result) – list of results (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 from the raw data (self._raw_data).
fit_data	Fit the RB results to an exponential curve.
fit_data_pattern	Fit the RB results of a particular pattern to an exponential curve.
plot_rb_data	Plot randomized benchmarking data of a single pattern.
