qiskit_aer.noise.mixed_unitary_error

mixed_unitary_error(noise_ops, standard_gates=None)

Return a mixed unitary quantum error channel.

The input should be a list of pairs (U[j], p[j]), where U[j] is a unitary matrix and p[j] is a probability. All probabilities must sum to 1 for the input ops to be valid.

Parameters

• noise_ops (list[pair[matrix, double]]) – unitary error matrices.
• standard_gates (bool) – DEPRECATED, Check if input matrices are standard gates.

Returns

The quantum error object.

Return type

QuantumError

Raises

NoiseError – if error parameters are invalid.
