cirq.experiments.xeb_fitting.fit_exponential_decays

Fit exponential decay curves to a fidelities DataFrame.

cirq.experiments.xeb_fitting.fit_exponential_decays(
    fidelities_df: pd.DataFrame
) -> pd.DataFrame

Args
`fidelities_df`	A DataFrame that is the result of `benchmark_2q_xeb_fidelities`. It may contain results for multiple pairs of qubits identified by the "pair" column. Each pair will be fit separately. At minimum, this dataframe must contain "cycle_depth", "fidelity", and "pair" columns.

Returns
A new, aggregated dataframe with index given by (pair, layer_i, pair_i); columns for the fit parameters "a" and "layer_fid"; and nested "cycles_depths" and "fidelities" lists (now grouped by pair).
