class deltakit.circuit.noise_channels.PauliChannel1(qubit: Qubit[T] | T, p_x: float = 0.0, p_y: float = 0.0, p_z: float = 0.0, *, tag: str | None = None)

Bases: OneQubitNoiseChannel[T], MultiProbabilityNoiseChannel[T]

A single qubit Pauli error channel with explicitly specified probabilities for each case.

Parameters:

• qubit (Qubit[T] | T) – The qubit to apply the custom noise channel to.

• p_x (float, optional) – Probability of applying an X operation, by default 0.0

• p_y (float, optional) – Probability of applying a Y operation, by default 0.0

• p_z (float, optional) – Probability of applying a Z operation, by default 0.0

Notes

Pauli Mixture:

1-px-py-pz: I

px: X

py: Y

pz: Z
