benchmark

QuantumVolumeBenchmark

Type:

Type[Benchmark]

num_circuits

The number of circuits to use. * Should be at least 100 for a meaningful QV experiment.

Type:

int

num_sigmas

The number of sample standard deviations to consider with for the threshold criteria. * Default by consensus is 2

Type:

int

choose_qubits_routine

The routine to select qubit layouts. * Default is “custom”.

Type:

Literal[“custom”]

custom_qubits_array

The physical qubit layouts to perform the benchmark on. * Default is [[0, 2]].

Type:

Optional[Sequence[Sequence[int]]]

qiskit_optim_level

The Qiskit transpilation optimization level. * Default is 3.

Type:

int

optimize_sqg

Whether Single Qubit Gate Optimization is performed upon transpilation. * Default is True.

Type:

bool

routing_method

The Qiskit transpilation routing method to use. * Default is “sabre”.

Type:

Literal[“basic”, “lookahead”, “stochastic”, “sabre”, “none”]

physical_layout

Whether the coupling map is restricted to qubits in the input layout or not. - “fixed”: Restricts the coupling map to only the specified qubits. - “batching”: Considers the full coupling map of the backend and circuit execution is batched per final layout. * Default is “fixed”

Type:

Literal[“fixed”, “batching”]

rem

Whether Readout Error Mitigation is applied in post-processing. When set to True, both results (readout-unmitigated and -mitigated) are produced. - Default is True.

Type:

bool

mit_shots

The measurement shots to use for readout calibration. * Default is 1_000.

Type:

int
