Multiple choice
Per this lesson, how is a CNOT (control qubit 0, target qubit 1) built from a CZ gate and Hadamards?
🔬 try it before you answer
Apply H to both qubits, then CZ, then H to both again
Apply H to the control qubit 0 before and after the CZ
Apply a single CZ(0,1) with no Hadamards at all
Apply H to the target qubit 1, then CZ(0,1), then H to qubit 1 again
