unitary_to_process_mx
(U)¶ Compute the super-operator which acts on (row)-vectorized density matrices from a unitary operator (matrix) U which acts on state vectors. This super-operator is given by the tensor product of U and conjugate(U), i.e. kron(U,U.conj).
Parameters: U (numpy array) – The unitary matrix which acts on state vectors. Returns: The super-operator process matrix. Return type: numpy array
