class iqm.benchmarks.readout_mitigation.M3IQM(system=None, iter_threshold=4096)#

Bases: M3Mitigation

M3 readout mitigation class modified to work with IQM devices.

Methods

_grab_additional_cals(qubits[, shots, ...])

Grab missing calibration data from backend.

cals_from_system([qubits, shots, method, ...])

Grab calibration data from system.
cals_from_system(qubits=None, shots=None, method=None, initial_reset=False, rep_delay=None, cals_file=None, async_cal=False, cal_id=None)#

Grab calibration data from system.

Parameters:

  • qubits (array_like) – Qubits over which to correct calibration data. Default is all.

  • shots (int) – Number of shots per circuit. min(1e4, max_shots).

  • method (str) – Type of calibration, ‘balanced’ (default for hardware), ‘independent’ (default for simulators), or ‘marginal’.

  • initial_reset (bool) – Use resets at beginning of calibration circuits, default=False.

  • rep_delay (float) – Delay between circuits on IBM Quantum backends.

  • cals_file (str) – Output path to write JSON calibration data to.

  • async_cal (bool) – Do calibration async in a separate thread, default is False.

Raises:

M3Error – Called while a calibration currently in progress.
