pygsti.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
