cirq.kron_factor_4x4_to_2x2s

Splits a 4x4 matrix U = kron(A, B) into A, B, and a global factor.

cirq.kron_factor_4x4_to_2x2s(
    matrix: np.ndarray
) -> Tuple[complex, np.ndarray, np.ndarray]

Requires the matrix to be the kronecker product of two 2x2 unitaries. Requires the matrix to have a non-zero determinant. Giving an incorrect matrix will cause garbage output.

Args
`matrix`	The 4x4 unitary matrix to factor.

Returns
A scalar factor and a pair of 2x2 unit-determinant matrices. The kronecker product of all three is equal to the given matrix.

Raises
`ValueError`	The given matrix can't be tensor-factored into 2x2 pieces.
