Function Documentation

__del__()

def qgd_python.N_Qubit_Decomposition.__del__

(

self

)

Destructor of the class.

Definition at line 111 of file N_Qubit_Decomposition.py.

get_quantum_circuit()

def qgd_python.N_Qubit_Decomposition.get_quantum_circuit

(

self

)

Export the unitary decomposition into Qiskit format.

Returns

Return with a Qiskit compatible quantum circuit.

Definition at line 168 of file N_Qubit_Decomposition.py.

list_operations()

def qgd_python.N_Qubit_Decomposition.list_operations	(		self,
			start_index = 1
	)

Lists the operations decomposing the initial unitary.

(These operations are the inverse operations of the operations bringing the intial matrix into unity.)

Parameters

start_index

The index of the first inverse operation

Definition at line 160 of file N_Qubit_Decomposition.py.

set_identical_blocks()

def qgd_python.N_Qubit_Decomposition.set_identical_blocks	(		self,
			identical_blocks
	)

Set the number of identical successive blocks during the subdecomposition of the qbit-th qubit.

Parameters

identical_blocks

A dictionary {'n': identical_blocks} labeling the number of successive identical layers used in the subdecomposition at the disentangling of the n-th qubit.

Definition at line 150 of file N_Qubit_Decomposition.py.

set_iteration_loops()

def qgd_python.N_Qubit_Decomposition.set_iteration_loops	(		self,
			iteration_loops
	)

Set the number of iteration loops during the subdecomposition of the qbit-th qubit.

Parameters

iteration_loops

A dictionary {'n': iteration_loops} labeling the number of iteration loops in each step of the subdecomposition.

Definition at line 140 of file N_Qubit_Decomposition.py.

set_max_layer_num()

def qgd_python.N_Qubit_Decomposition.set_max_layer_num	(		self,
			max_layer_num
	)

Set the maximal number of layers used in the subdecomposition of the qbit-th qubit.

Parameters

max_layer_num

A dictionary {'n': max_layer_num} labeling the maximal number of the operation layers used in the subdecomposition.

Definition at line 131 of file N_Qubit_Decomposition.py.

set_optimalization_block()

def qgd_python.N_Qubit_Decomposition.set_optimalization_block	(		self,
			optimalization_block
	)

Call to set the number of blocks to be optimized in one shot.

Parameters

optimalization_block

The number of blocks to be optimized in one shot

Definition at line 230 of file N_Qubit_Decomposition.py.

set_verbose()

def qgd_python.N_Qubit_Decomposition.set_verbose	(		self,
			verbose
	)

Set the verbosity of the N_Qubit_Decomposition class.

Parameters

verbose

Set False to suppress the output messages of the decompostion, or True (deafult) otherwise.

Definition at line 221 of file N_Qubit_Decomposition.py.

start_decomposition()

def qgd_python.N_Qubit_Decomposition.start_decomposition	(		self,
			finalize_decomposition = True
	)

Start the disentanglig process of the least significant two qubit unitary.

Parameters

finalize_decomposition

Optional logical parameter. If true (default), the decoupled qubits are rotated into state |0> when the disentangling of the qubits is done. Set to False to omit this procedure

Definition at line 122 of file N_Qubit_Decomposition.py.
