WebMay 27, 2024 · Welcome to XOR (exclusive OR), which solves this problem, much in line with standard human reasoning. This logic gate works like this: 0 + 0 => 0 0 + 1 => 1 1 + 0 => 1 1 + 1 => 0 The input and output are the same as our OR gate, but this time, the input really does need to be exclusive.

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 … WebJul 7, 2015 · Take 2 numbers : A=1011 and B=1010. if the i th bit of A is 1 then shift B i times to the left. So in the end you will get something like. 1010 1010 1010. So now you Apply XOR on these numbers which results in : 00001010 00010100 (XOR) 01010000 (XOR) --------- 01001110.

WebJan 23, 2014 · 1. Given that (a-b) (a-b) quite obviously computes xor for a single bit, you could construct a function with the floor or mod arithmetic operators to split the bits out, then xor them, then sum to recombine. (a-b) (a-b) = a2 -2·a·b + b2 so one bit of xor gives a polynomial with 3 terms. theprogamerjayWebNov 24, 2011 · C = S [ M ⊕ k], where C is ciphertext, M is the plaintext message, k is the key and S is an S-box.

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. theprogamerjay youtube
