*Perform the cloner circuit. the cloner circuit consists of four CNOT gate acting in all the three input qubits. For every CNOT gate, we have a control qubit (which indicates whether or not the CNOT should act) and a target qubit (which is the qubit that CNOT gate acts on it and flips it). | *Perform the cloner circuit. the cloner circuit consists of four CNOT gate acting in all the three input qubits.
