iqm.benchmarks.entanglement.ghz.fidelity_ghz_coherences

iqm.benchmarks.entanglement.ghz.fidelity_ghz_coherences(dataset: Dataset, qubit_layout: List[int], circuits: Circuits) → list[Any]

Estimates the GHZ state fidelity based on the multiple quantum coherences method based on [Mooney, 2021]

Parameters:

• dataset (Dataset) – xr.Dataset An xarray dataset containing the measurement data

• qubit_layout (List[int]) – List[int] The subset of system-qubits used in the protocol

• circuits (Circuits) – Circuits Instance of Circuits containing transpiled circuits

Returns:

The ghz fidelity or, if rem=True, fidelity and readout error mitigated fidelity

Return type:

dict[str, dict[str, Any]]
