Shor's algorithm is a polynomial-time quantum computer algorithm for integer factorization. Informally, it solves the following problem: Given an integer, find its prime factors. It was invented in 1994 by the American mathematician Peter Shor The quantum search algorithm is sometimes described as a database search algorithm. This is often done in popular media accounts, and sometimes even in research papers. Unfortunately, it's not a terribly helpful way of thinking about it

Quantum Adiabatic Algorithm (QADI) Among the many known quantum algorithms, QADI, introduced by Farhi et al. in 2000 as an alternative to classical heuristics for hard optimization problems, is an especially good match for our target systems. QADI involves building a system that can slowly evolve from an instance-independent Hamiltonian H(0) to a final H(T) whose lowest energy state encodes. As we begin to reach the limits of classical computing, quantum computing has emerged as a technology that has captured the imagination of the scientific world.
