Question 404

Making two qubits linked

Which circuit pattern can create entanglement from two qubits initially in |00⟩?

A

Apply H to the first qubit, then CNOT from the first to the second

B

Apply H to both qubits, then CNOT from the first to the second

C

Apply CNOT from the first to the second, then H to the first

D

Apply H to the first qubit, then SWAP the first and second
