WebNov 10, 2024 · Modern crypto algorithms, which are vastly more complicated than XOR (though they may use XOR as part of the full cryptographic scheme), have ways of "stretching" a key so it can encrypt data longer then itself, without exposing the key (even indirectly) the way XOR does. This is, for example, how all stream ciphers work; they … 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.
