deltakit.circuit.noise_channels.ElseCorrelatedError

class deltakit.circuit.noise_channels.ElseCorrelatedError(pauli_product: PauliX[T] | PauliY[T] | PauliZ[T] | Iterable[PauliX[T] | PauliY[T] | PauliZ[T]] | PauliProduct[T], probability: float, tag: str | None = None)

Bases: PauliProductNoise[T]

Probabilistically applies a Pauli product error with a given probability, unless the “correlated error occurred flag” is set. If the error occurs, sets the “correlated error occurred flag” to true. Otherwise leaves the flag alone.

Parameters:

• pauli_product (PauliGateT | Iterable[PauliGateT] | PauliProduct[T]) – The Pauli gates specifying the Paulis to apply when the error occurs.

• probability (float) – A single float specifying the probability of applying the Paulis making up the error.

Methods

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