Question: Suppose we make a 2-qubit gate that (on classical inputs) ⊕s the value of qubit 1 into qubit 2, while leaving qubit 1 alone. Write out the truth table for this 2-qubit gate. Have we seen it before? What is the output of this gate when qubit 1 and qubit 2 are initialized to Hadamard(|0?)= |0?+ |1? and Hadamard(|1?)= |0?- |1?, respectively? Are the two qubits entangled in the output state? Did the state of qubit 1 change? What about qubit 2?
