Bases: object

static get_csd(unitary_mats)

This function does a CS (cosine-sine) decomposition (by calling the LAPACK function cuncsd.f. The old C++ Qubiter called zggsvd.f instead) of each unitary matrix in the list of arrays unitary_mats. This function is called by the constructor of the class Node and is fundamental for decomposing a unitary matrix into multiplexors and diagonal unitaries.

Parameters:unitary_mats (list(np.ndarray)) – Returns: Return type:list(np.ndarray), list(np.ndarray), list(np.ndarray)
