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 (ParameterValueType) – The angle of the rotation.
control_qubit (QubitSpecifier) – The qubit(s) used as the control.
target_qubit (QubitSpecifier) – The qubit(s) targeted by the gate.
label (str | None) – The string label of the gate in the circuit.
ctrl_state (str | int | None) – The control state in decimal, or as a bitstring (e.g. ‘1’). Defaults to controlling on the ‘1’ state.
- Returns
A handle to the instructions created.
