Bases: `types.SimpleNamespace`
|
||
|
||
A configuration for a QASM Qobj.
|
||
|
||
Model for RunConfig.
|
||
|
||
**Parameters**
|
||
|
||
* **shots** (*int*) – the number of shots.
|
||
* **max\_credits** (*int*) – DEPRECATED This parameter is deprecated as of Qiskit Terra 0.20.0, and will be removed in a future release. This parameter has no effect on modern IBM Quantum systems, and no alternative is necessary.
|
||
* **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`](qiskit.qobj.PulseLibraryItem "qiskit.qobj.PulseLibraryItem").
|
||
* **calibrations** ([*QasmExperimentCalibrations*](qiskit.qobj.QasmExperimentCalibrations "qiskit.qobj.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.
