Shor's quantum factoring algorithm
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 $${\displaystyle N}$$, Shor's algorithm runs in polylogarithmic time, meaning the time taken is polynomial in Prikaži več The problem that we are trying to solve is, given a composite number $${\displaystyle N}$$, to find a non-trivial divisor of $${\displaystyle N}$$ (a divisor strictly between $${\displaystyle 1}$$ and $${\displaystyle N}$$). … Prikaži več • GEECM, a factorization algorithm said to be "often much faster than Shor's" • Grover's algorithm Prikaži več • Nielsen, Michael A. & Chuang, Isaac L.

Splet09. avg. 2024 · Shor's algorithm can be thought of as a hybrid algorithm. The quantum computer is used to perform a computationally hard task known as period finding. The results from period finding are then classically processed to estimate the factors. We review these two steps below.
