FakeBackendV2 initializer. ## Attributes ### backend\_name ### conf\_filename ### coupling\_map Return the `CouplingMap` object ### defs\_filename ### dirname ### dt Return the system time resolution of input signals This is required to be implemented if the backend supports Pulse scheduling. **Return type** `Optional`\[`float`] **Returns** The input signal timestep in seconds. If the backend doesn’t define `dt`, `None` will be returned. ### dtm Return the system time resolution of output signals **Return type** `float` **Returns** The output signal timestep in seconds. ### instruction\_durations Return the `InstructionDurations` object. ### instruction\_schedule\_map Return the `InstructionScheduleMap` for the instructions defined in this backend’s target. ### instructions A list of Instruction tuples on the backend of the form `(instruction, (qubits)` **Return type** `List`\[`Tuple`\[`Instruction`, `Tuple`\[`int`]]] ### max\_circuits **Return type** `None` ### meas\_map Return the grouping of measurements which are multiplexed This is required to be implemented if the backend supports Pulse scheduling. **Return type** `List`\[`List`\[`int`]] **Returns** The grouping of measurements which are multiplexed ### num\_qubits Return the number of qubits the backend has. **Return type** `int` ### operation\_names A list of instruction names that the backend supports. **Return type** `List`\[`str`] ### operations A list of `Instruction` instances that the backend supports. **Return type** `List`\[`Instruction`] ### options Return the options for the backend The options of a backend are the dynamic parameters defining how the backend is used. These are used to control the [`run()`](#qiskit_ibm_runtime.fake_provider.FakePeekskill.run "qiskit_ibm_runtime.fake_provider.FakePeekskill.run") method. ### props\_filename ### provider Return the backend Provider. **Returns** the Provider responsible for the backend. **Return type** Provider ### target A `qiskit.transpiler.Target` object for the backend. **Return type** Target ### version ### name Name of the backend. ### description Optional human-readable description. ### online\_date Date that the backend came online. ### backend\_version Version of the backend being provided. This is not the same as `BackendV2.version`, which is the version of the `Backend` abstract interface. ## Methods ### acquire\_channel Return the acquisition channel for the given qubit. This is required to be implemented if the backend supports Pulse scheduling. **Returns** The Qubit measurement acquisition line. **Return type** AcquireChannel ### control\_channel Return the secondary drive channel for the given qubit This is typically utilized for controlling multiqubit interactions. This channel is derived from other channels. This is required to be implemented if the backend supports Pulse scheduling. **Parameters** **qubits** (`Iterable`\[`int`]) – Tuple or list of qubits of the form `(control_qubit, target_qubit)`. **Returns** The multi qubit control line. **Return type** List\[ControlChannel] ### drive\_channel Return the drive channel for the given qubit. This is required to be implemented if the backend supports Pulse scheduling. **Returns** The Qubit drive channel **Return type** DriveChannel ### measure\_channel Return the measure stimulus channel for the given qubit. This is required to be implemented if the backend supports Pulse scheduling. **Returns** The Qubit measurement stimulus line **Return type** MeasureChannel ### qubit\_properties Return QubitProperties for a given qubit. If there are no defined or the backend doesn’t support querying these details this method does not need to be implemented. **Parameters** **qubit** (`Union`\[`int`, `List`\[`int`]]) – The qubit to get the `QubitProperties` object for. This can be a single integer for 1 qubit or a list of qubits and a list of `QubitProperties` objects will be returned in the same order **Return type** `Union`\[`QubitProperties`, `List`\[`QubitProperties`]] **Returns** The `QubitProperties` object for the specified qubit. If a list of qubits is provided a list will be returned. If properties are missing for a qubit this can be `None`. **Raises** **NotImplementedError** – if the backend doesn’t support querying the qubit properties ### run Run on the fake backend using a simulator. This method runs circuit jobs (an individual or a list of QuantumCircuit ) and pulse jobs (an individual or a list of Schedule or ScheduleBlock) using BasicSimulator or Aer simulator and returns a `Job` object. If qiskit-aer is installed, jobs will be run using AerSimulator with noise model of the fake backend. Otherwise, jobs will be run using BasicSimulator without noise. Currently noisy simulation of a pulse job is not supported yet in FakeBackendV2. **Parameters** * **run\_input** (*QuantumCircuit or Schedule or ScheduleBlock or list*) – An individual or a list of `QuantumCircuit`, `ScheduleBlock`, or `Schedule` objects to run on the backend. * **options** – Any kwarg options to pass to the backend for running the config. If a key is also present in the options attribute/object then the expectation is that the value specified will be used instead of what’s set in the options object. **Returns** The job object for the run **Return type** Job **Raises** **QiskitError** – If a pulse job is supplied and qiskit-aer is not installed. ### set\_options Set the options fields for the backend This method is used to update the options of a backend. If you need to change any of the options prior to running just pass in the kwarg with the new value for the options. **Parameters** **fields** – The fields to update the options **Raises** **AttributeError** – If the field passed in is not part of the options
