GK Question

technology hard fill_blank

The quantum algorithm that can factor large integers exponentially faster than classical algorithms is ________ Algorithm.

Answer: Shor's

Shor's Algorithm (1994) factors integers in polynomial time on a quantum computer, threatening RSA encryption which relies on factoring difficulty. Requires fault-tolerant quantum computers not yet available. Grover's Algorithm provides quadratic speedup for unstructured search. Critical for cryptography and quantum advantage questions.
