Did you know?
Shor's algorithm is a quantum computer algorithm for finding the prime factors of an integer. It was developed in 1994 by the American mathematician Peter Shor. On a quantum computer, to factor an integer , Shor's algorithm runs in polylogarithmic time, meaning the time taken is polynomial in , the size of the integer given as input. Specifically, it takes quantum gates of order using fast multiplication, or even utilizing the asymptotically fastest multipl… Nettet3. nov. 2024 · Shor's algorithm can be used to factorize a large (semi)prime N by reducing the task to period-finding of a function f ( x) = x a mod N. This is done by creating an equal superposition over all pairs of a i and f ( x) = x a i for a random x, then measuring f ( x) causing the superposition to collapse into all a i for which f ( x) is our ...
