Bases: SimpleNamespace

A configuration for an OpenQASM 2 Qobj.

Model for RunConfig.

Parameters

  • shots (int) – the number of shots.
  • seed_simulator (int) – the seed to use in the simulator
  • memory (bool) – whether to request memory from backend (per-shot readouts)
  • parameter_binds (list[dict]) – List of parameter bindings
  • meas_level (int) – Measurement level 0, 1, or 2
  • meas_return (str) – For measurement level < 2, whether single or avg shots are returned
  • memory_slots (int) – The number of memory slots on the device
  • n_qubits (int) – The number of qubits on the device
  • pulse_library (list) – List of PulseLibraryItem.
  • calibrations (QasmExperimentCalibrations) – Information required for Pulse gates.
  • rep_delay (float) – Delay between programs in sec. Only supported on certain backends (backend.configuration().dynamic_reprate_enabled ). Must be from the range supplied by the backend (backend.configuration().rep_delay_range). Default is backend.configuration().default_rep_delay.
  • qubit_lo_freq (list) – List of frequencies (as floats) for the qubit driver LO’s in GHz.
  • meas_lo_freq (list) – List of frequencies (as floats) for the measurement driver LO’s in GHz.
  • kwargs – Additional free form key value fields to add to the configuration.
