QasmQobjConfig

class qiskit.qobj.QasmQobjConfig(shots=None, seed_simulator=None, memory=None, parameter_binds=None, meas_level=None, meas_return=None, memory_slots=None, n_qubits=None, pulse_library=None, calibrations=None, rep_delay=None, qubit_lo_freq=None, meas_lo_freq=None, **kwargs)

Bases: SimpleNamespace

A configuration for an OpenQASM 2 Qobj.

Model for RunConfig.

Deprecated since version 1.2

The class qiskit.qobj.qasm_qobj.QasmQobjConfig is deprecated as of qiskit 1.2. It will be removed in the 2.0 release. The Qobj class and related functionality are part of the deprecated BackendV1 workflow, and no longer necessary for BackendV2. If a user workflow requires Qobj it likely relies on deprecated functionality and should be updated to use BackendV2.

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.
