cunqa.circuit.circuit.ControlContext

class cunqa.circuit.circuit.ControlContext(control_circuit: CunqaCircuit, target_circuit: CunqaCircuit)

Bases: object

Class to manage the controlled telegate operations from a circuit/virtual QPU to another.

An object of this class is returned by the expose() method. Used as a context manager, it can be passed to controlled operations in order to implement telgate operations:

>>> with circuit_1.expose(0, circuit_2) as rcontrol:
>>>     circuit_2.cx(rcontrol, 0)

Then, when the block ends, the ControlContext adds the propper “rcontrol” instruction to the target circuit.

Methods

ControlContext.__init__(control_circuit: CunqaCircuit, target_circuit: CunqaCircuit) → int

Class constructor.

Parameters:

  • control_circuit (CunqaCircuit) – circuit which qubit is exposed.

  • target_circuit (CunqaCircuit) – circuit in which the instructions are implemented.
