deltakit.circuit.noise_channels.Depolarise1

class deltakit.circuit.noise_channels.Depolarise1(qubit: Qubit[T] | T, probability: float, *, tag: str | None = None)

Bases: OneQubitOneProbabilityNoiseChannel[T]

The one-qubit depolarising channel. Applies a randomly chosen Pauli with a given probability.

Parameters:

• qubit (Qubit[T] | T) – The qubit to apply one-qubit depolarising noise to.

• probability (float) – A single float specifying the depolarisation strength.

Notes

Pauli Mixture:

1-p: I

p/3: X

p/3: Y

p/3: Z

Methods

Depolarise1.approx_equals	Determine whether two noise channels are equal within a given tolerance.
Depolarise1.generator_from_prob	Return a classmethod that can be used to create a noise channel with a predetermined probability
Depolarise1.stim_targets	Return all the stim targets which specifies this noise channel.
Depolarise1.transform_qubits	Transform this noise channel's qubits according to the id mapping.
