qiskit.circuit.QuantumCircuit.cp¶
- QuantumCircuit.cp(theta, control_qubit, target_qubit, label=None, ctrl_state=None)[source]¶
Apply
CPhaseGate.For the full matrix form of this gate, see the underlying gate documentation.
- Parameters
theta (
Union[ParameterExpression,float]) – The angle of the rotation.control_qubit (
Union[Qubit,QuantumRegister,int,slice,Sequence[Union[Qubit,int]]]) – The qubit(s) used as the control.target_qubit (
Union[Qubit,QuantumRegister,int,slice,Sequence[Union[Qubit,int]]]) – The qubit(s) targeted by the gate.label (
Optional[str]) – The string label of the gate in the circuit.ctrl_state (
Union[str,int,None]) – The control state in decimal, or as a bitstring (e.g. ‘1’). Defaults to controlling on the ‘1’ state.
