class mindquantum.core.circuit.UN(gate: BasicGate, maps_obj, maps_ctrl=None)#

Map a quantum gate to different objective qubits and control qubits.

Parameters:

  • gate (BasicGate) – A quantum gate.

  • maps_obj (Union[int, list[int]]) – Objective qubits.

  • maps_ctrl (Union[int, list[int]]) – Control qubits. Default: None.

Returns:

Circuit, Return a quantum circuit.

Examples

>>> from mindquantum.core.circuit import UN
>>> from mindquantum.core.gates import X
>>> circuit1 = UN(X, maps_obj = [0, 1], maps_ctrl = [2, 3])
>>> print(circuit1)
