PauliNoiseChannel#

class cuquantum.pauliprop.experimental.PauliNoiseChannel( qubit_indices: Sequence[int], noise_probabilities: Mapping[str, float], )[source]#

A Pauli noise channel acting on 1 or 2 qubits.

Methods

__init__( qubit_indices: Sequence[int], noise_probabilities: Mapping[str, float], )[source]#

Create a Pauli noise channel.

Parameters:

qubit_indices – The qubit indices the channel acts on (1 or 2 qubits).
noise_probabilities – A dictionary mapping Pauli strings to their probabilities. Pauli strings not present in the dictionary are assumed to have zero probability. For single-qubit channels, valid keys are “I”, “X”, “Y”, “Z”. For two-qubit channels, valid keys are “II”, “XI”, “YI”, “ZI”, “IX”, etc.

Attributes

noise_paulis#: The Pauli strings in reference order corresponding to each probability, see noise_probabilities for the corresponding probabilities.

noise_probabilities#: The noise probabilities in reference Pauli order, see noise_paulis for the corresponding Pauli strings.

qubit_indices#: The qubit indices this channel acts on.
