WebDec 23, 2024 · 1 Answer. You can't directly use a classical XOR gate inside a quantum circuit because the usual construction of such a gate is a classical construction - it won't preserve coherence. In other words, it will function just fine if you input a 0 or a 1 as each input, but it won't perform as you'd need it to if you supplied it with a superposition.
