Computer scientist and mathematician Peter Shor, a principal research scientist at AT&T Labs (Florham, N.J.), is the recipient of Carnegie Mellon University=B9s 1998 Dickson Prize in Science for his pioneering research in the theory of quantum computing.
However, the possibilities of such a device were not appreciated until 1994, when Shor discovered an algorithm for factoring large integers or whole numbers into prime numbers on a quantum computer.
However, a device which could actually carry out Shor's algorithm for large numbers is still many years away, because numerous technical difficulties have to be overcome.

Richard Feynman's observation that quantum mechanical effects could not be simulated efficiently on a computer led to speculation that computation in general could be done more efficiently if it used quantum effects.
This speculation appeared justified when Peter Shor described a polynomial time quantum algorithm for factoring integers.
Various approaches to harnessing the power of quantum parallelism are explained, including Shor's algorithm, Grover's algorithm, and Hogg's algorithms.
