IBMQBackend.run(circuits, job_name=None, job_share_level=None, job_tags=None, experiment_id=None, header=None, shots=None, memory=None, qubit_lo_freq=None, meas_lo_freq=None, schedule_los=None, meas_level=None, meas_return=None, memory_slots=None, memory_slot_size=None, rep_time=None, rep_delay=None, init_qubits=None, parameter_binds=None, use_measure_esp=None, live_data_enabled=None, **run_config)[source]

Run on the backend.

If a keyword specified here is also present in the options attribute/object, the value specified here will be used for this run.

Parameters

  • circuits (Union[QasmQobj, PulseQobj, QuantumCircuit, Schedule, List[Union[QuantumCircuit, Schedule]]]) – An individual or a list of QuantumCircuit or Schedule objects to run on the backend. A QasmQobj or a PulseQobj object is also supported but is deprecated.

  • job_name (Optional[str]) – Custom name to be assigned to the job. This job name can subsequently be used as a filter in the jobs() method. Job names do not need to be unique.

  • job_share_level (Optional[str]) –

    Allows sharing a job at the hub, group, project, or global level. The possible job share levels are: global, hub, group, project, and none.

    • global: The job is public to any user.

    • hub: The job is shared between the users in the same hub.

    • group: The job is shared between the users in the same group.

    • project: The job is shared between the users in the same project.

    • none: The job is not shared at any level.

    If the job share level is not specified, the job is not shared at any level.

  • job_tags (Optional[List[str]]) – Tags to be assigned to the job. The tags can subsequently be used as a filter in the jobs() function call.

  • experiment_id (Optional[str]) – Used to add a job to an “experiment”, which is a collection of jobs and additional metadata.

  • in. (The following arguments are NOT applicable if a Qobj is passed) –

  • header (Optional[Dict]) – User input that will be attached to the job and will be copied to the corresponding result header. Headers do not affect the run. This replaces the old Qobj header.

  • shots (Optional[int]) – Number of repetitions of each circuit, for sampling. Default: 4000 or max_shots from the backend configuration, whichever is smaller.

  • memory (Optional[bool]) – If True, per-shot measurement bitstrings are returned as well (provided the backend supports it). For OpenPulse jobs, only measurement level 2 supports this option.

  • qubit_lo_freq (Optional[List[int]]) – List of default qubit LO frequencies in Hz. Will be overridden by schedule_los if set.

  • meas_lo_freq (Optional[List[int]]) – List of default measurement LO frequencies in Hz. Will be overridden by schedule_los if set.

  • schedule_los (Union[List[Union[Dict[PulseChannel, float], LoConfig]], Dict[PulseChannel, float], LoConfig, None]) – Experiment LO configurations, frequencies are given in Hz.

  • meas_level (Union[int, MeasLevel, None]) – Set the appropriate level of the measurement output for pulse experiments.

  • meas_return (Union[str, MeasReturnType, None]) –

    Level of measurement data for the backend to return.

    For meas_level 0 and 1:

    • single returns information from every shot.

    • avg returns average measurement output (averaged over number of shots).

  • memory_slots (Optional[int]) – Number of classical memory slots to use.

  • memory_slot_size (Optional[int]) – Size of each memory slot if the output is Level 0.

  • rep_time (Optional[int]) – Time per program execution in seconds. Must be from the list provided by the backend (backend.configuration().rep_times). Defaults to the first entry.

  • rep_delay (Optional[float]) – Delay between programs in seconds. Only supported on certain backends (if backend.configuration().dynamic_reprate_enabled=True). If supported, rep_delay will be used instead of rep_time and must be from the range supplied by the backend (backend.configuration().rep_delay_range). Default is given by backend.configuration().default_rep_delay.

  • init_qubits (Optional[bool]) – Whether to reset the qubits to the ground state for each shot. Default: True.

  • parameter_binds (Optional[List[Dict[Parameter, float]]]) – List of Parameter bindings over which the set of experiments will be executed. Each list element (bind) should be of the form {Parameter1: value1, Parameter2: value2, …}. All binds will be executed across all experiments; e.g., if parameter_binds is a length-n list, and there are m experiments, a total of m x n experiments will be run (one for each experiment/bind pair).

  • use_measure_esp (Optional[bool]) – Whether to use excited state promoted (ESP) readout for measurements which are the terminal instruction to a qubit. ESP readout can offer higher fidelity than standard measurement sequences. See here. Default: True if backend supports ESP readout, else False. Backend support for ESP readout is determined by the flag measure_esp_enabled in backend.configuration().

  • live_data_enabled (bool) – Activate the live data in the backend, to receive data from the instruments.

  • **run_config – Extra arguments used to configure the run.
