(V, tol=1e-11)[source]¶ Rectangular decomposition of a unitary matrix, with all local phase shifts placed after the interferometers.
See [23] for more details.
Final step in the decomposition of a given discrete unitary matrix. The output is of the form given in Eq. 5.
- Parameters
V (array[complex]) – unitary matrix of size n_size
tol (float) – the tolerance used when checking if the matrix is unitary
- Returns
- returns a tuple of the form
(tlist, np.diag(localV), None)
where:
tlist
: list containing[n,m,theta,phi,n_size]
of the T unitaries neededlocalV
: Diagonal unitary matrix to be applied at the end of circuit
- returns a tuple of the form
- Return type
tuple[array]
