This algorithm can speed up an unstructured search problem quadratically, … WebFeb 9, 2024 · Grover's algorithm will need to compute the hash function in superposition, and it needs to compute the entire hash function, whatever the nonce is. This means we need at least 512 qubits (256 for the input, 256 for the input) and in practice the number would be more like 5000 qubits.
WebGrover's Algorithm uses 2 simple tricks to search an unordered database (like a phonebook that contains names and phone numbers but not in alphabetical order). It inputs an equal superposition of all possible entries and searches the database in one operation. When it finds the matching entry, it marks it by flipping the sign of the ...
