Trigger

QuICT.core.operator.Trigger 

Trigger(targets: int, state_gate_mapping: Union[dict, list, tuple, FunctionType], position: Union[int, list] = None, name: str = None)

Bases: Operator

The trigger for switch the dynamic circuit; contains the target qubits and related circuits with different state.

Parameters:

  • targets (int) –

    The number of target qubits.

  • state_gate_mapping (Union[dict, list, tuple, FunctionType]) –

    The mapping of state and related composite gates. (Union[Dict[int, CompositeGate], List[CompositeGate], Tuple[CompositeGate], FunctionType])

  • position (int, default: None ) –

    The insert position for mapping CompositeGate into Circuit.

  • name (str, default: None ) –

    The name of current trigger, Default to Trigger.

Raises:

mapping(state: int)

Return the related composite gate with given qubits' measured state.

Parameters:

  • state (int) –

    The qubits' measured state.

Returns:

  • CompositeGate –

    The related composite gate.
