class discopy.quantum.gates.Controlled(name=None, dom=None, cod=None, data=None, *args, **kwargs)[source]#

Abstract class for controled quantum gates.

Parameters:

controlled (QuantumGate) – Gate to control, e.g. CX = Controlled(X).
distance (int, optional) – Number of qubits from the control to the target, default is 0. If negative, the control is on the right of the target.
(Controlled(CX.l (>>> circuit =)
distance=3)
Controlled(Controlled(CZ.l (... >>)
distance=2)
distance=-1))
circuit.draw( (>>>)
wire_labels=False (...)
