qiskit.circuit.QuantumCircuit.fredkin

QuantumCircuit.fredkin(control_qubit, target_qubit1, target_qubit2)

Apply CSwapGate.

For the full matrix form of this gate, see the underlying gate documentation.

Parameters

• control_qubit (Union[Qubit, QuantumRegister, int, slice, Sequence[Union[Qubit, int]]]) -- The qubit(s) used as the control.

• target_qubit1 (Union[Qubit, QuantumRegister, int, slice, Sequence[Union[Qubit, int]]]) -- The qubit(s) targeted by the gate.

• target_qubit2 (Union[Qubit, QuantumRegister, int, slice, Sequence[Union[Qubit, int]]]) -- The qubit(s) targeted by the gate.

Returns

A handle to the instructions created.
