Overview of quantum computing
A quantum computer is a device that performs computation by controlling and measuring quantum states. Quantum computers were first proposed in the 1980s by several physicists, notably Paul Benioff, David Deutsch, Richard Feynman, and Yuri Manin. It is widely believed that quantum computers should be capable of performing computations that would not be feasible on a classical computer, particulary problems in computational chemistry which require the simulation of quantum states.
