Function Documentation

__init__()

def squander.decomposition.qgd_N_Qubit_Decomposition.__init__	(		self,
			Umtx,
			optimize_layer_num = False,
			initial_guess = "RANDOM"
	)

Constructor of the class.

Parameters

Umtx	The unitary matrix to be decomposed.
optimize_layer_num	Set true to optimize the minimum number of operation layers required in the decomposition, or false when the predefined maximal number of layer gates is used (ideal for general unitaries).
initial_guess	String indicating the method to guess initial values for the optimalization. Possible values: "zeros" ,"random", "close_to_zero".

Returns

An instance of the class
