mixed_unitary_error

mixed_unitary_error(noise_ops, standard_gates=True)[source]

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) – Check if input matrices are standard gates.

Returns

The quantum error object.

Return type

QuantumError

Raises

NoiseError – if error parameters are invalid.
