Web1 day ago · An important protocol in quantum networks and cryptography, quantum state sharing works like this (in simple terms): a secret quantum state is divided into n shares and given to n players. The secret state can only be reconstructed if k (where k > n /2) players cooperate, while the remaining n - k players cannot access the information.

Cryptographic hash functions must be deterministic. In other words, for any given input, a hash function must always give the same result. If you put in the same input ten million times in a row, a hash function must produce the same exact output ten million times over. This may also be rather obvious.
