Returns the matrix representation of an operation in standard basis.

cirq.operation_to_superoperator(
    operation: 'protocols.SupportsKraus'
) -> np.ndarray

Let E: L(H1) -> L(H2) denote a linear map which takes linear operators on Hilbert space H1 to linear operators on Hilbert space H2 and let d1 = dim H1 and d2 = dim H2. Also, let Fij denote an operator whose matrix has one in ith row and jth column and zeros everywhere else. Note that d1-by-d1 operators Fij form a basis of L(H1). Similarly, d2-by-d2 operators Fij form a basis of L(H2). This function returns the matrix of E in these bases.
