Overview: An algorithm is a step-by-step set of instructions that takes an input and produces a clear output, just like a ...

A quantum computer algorithm that is used to find the prime factors in an encryption key. Created by applied mathematician Peter Shor in the mid-1990s, Shor's algorithm may be used to break the codes ...

Other work has focussed on understanding which quantum systems can be simulated efficiently on a classical computer. This work should lead to the definition of some simulation problems that are not ...

The most widely used technique for finding the largest or smallest values of a math function turns out to be a fundamentally difficult computational problem. Many aspects of modern applied research ...
