Bases: object

Dataclass to capture a noise model for a quantum computer.

Parameters:

• gate_noise (Dict[Type[Gate], Callable[[Gate], NoiseChannel]]) – Noise to be added after applying a gate. This is specified through a dictionary with gate classes as keys and functions which take a gate and return a noise channel as values. The noise can thus be different for each gate class and can be dependent on the qubit(s) involved in the gate. By default, there is no noise.

• idle_noise (Optional[Callable[[Qubit, float], NoiseChannel]]) – Noise to be added to an idle qubit. This can be dependent on the qubit and the time for which it is idle. By default, there is no noise.

• reset_noise (Optional[Callable[[OneQubitResetGate], NoiseChannel]]) – Noise to be added after resetting a qubit. This can be dependent on the reset gate applied and the qubit involved. By default, there is no noise.

• measurement_noise_after (Optional[Callable[[OneQubitMeasurementGate], NoiseChannel]]) – Noise to be added after measuring a qubit. This can be dependent on the measurement gate applied and the qubit involved. By default, there is no noise.

• measurement_flip (Optional[Callable[[_MeasurementGate], _MeasurementGate]]) – Mapping from a measurement gate to a noisy measurement gate, capturing adding error associated with obtaining an incorrect measurement result. By default, there is no noise.

• measurement_noise_before (Optional[Callable[[OneQubitMeasurementGate], NoiseChannel]]) – Noise which will be applied before a measurement gate. By default, there is no noise.

Raises:

ValueError – If any key in gate_noise is not a one-qubit or two-qubit gate.

Methods

NoiseParameters.as_noise_profile_after_gate
