PurityRBFitter¶

class PurityRBFitter(purity_result, npurity, cliff_lengths, rb_pattern=None)[source]¶

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

Class for fitter for purity RB.

Derived from RBFitterBase class.

Parameters

purity_result (list) – list of results of the 3^n purity RB sequences per seed (qiskit.Result).
npurity (int) – equals 3^n (where n is the dimension).
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

`F234`	Function than maps: 2^n x 3^n –> 4^n , namely: (a,b) –> c where a in 2^n, b in 3^n, c in 4^n
`add_data`	Add a new result.
`add_zdict_ops`	Creating all Z-correlators in order to compute the expectation values.
`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 Purity 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 purity RB data of a single pattern.
