PulseQobjConfig

class qiskit.qobj.PulseQobjConfig(meas_level, meas_return, pulse_library, qubit_lo_freq, meas_lo_freq, memory_slot_size=None, rep_time=None, rep_delay=None, shots=None, seed_simulator=None, memory_slots=None, **kwargs)

Bases: QobjDictField

A configuration for a Pulse Qobj.

Instantiate a PulseQobjConfig object.

Deprecated since version 1.2

The class qiskit.qobj.pulse_qobj.PulseQobjConfig 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

  • meas_level (int) – The measurement level to use.
  • meas_return (int) – The level of measurement information to return.
  • pulse_library (list) – A list of PulseLibraryItem objects which define the set of primitive pulses
  • 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.
  • memory_slot_size (int) – Size of each memory slot if the output is Level 0.
  • rep_time (int) – Time per program execution in sec. Must be from the list provided by the backend (backend.configuration().rep_times). Defaults to the first entry in backend.configuration().rep_times.
  • rep_delay (float) – Delay between programs in sec. Only supported on certain backends (backend.configuration().dynamic_reprate_enabled ). 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 backend.configuration().default_rep_delay.
  • shots (int) – The number of shots
  • seed_simulator (int) – the seed to use in the simulator
  • memory_slots (list) – The number of memory slots on the device
  • kwargs – Additional free form key value fields to add to the configuration
