quantum computer

quantum computer [′kwän·təm kəm¦pyüd·ər]
(computer science)
A computer in which the time evolution of the state of the individual switching elements of the computer is governed by the laws of quantum mechanics.
(computer)quantum computer - A type of computer which uses the ability of quantum systems, such as a collection of atoms, to be in many different states at once. In theory, such superpositions allow the computer to perform many different computations simultaneously. This capability is combined with interference among the states to produce answers to some problems, such as factoring integers, much more rapidly than is possible with conventional computers. In practice, such machines have not yet been built due to their extreme sensitivity to noise.

Oxford University, Stanford University.

A quantum search algorithm for constraint satisfaction problems exhibits the phase transition for NP-complete problems.

Quantum computers will reduce the time to solve some complex problems from years to seconds, and quantum algorithms will lead to radical improvements in the efficiency of data search.
The future of work-cubed by Rubens, Kevin / People & Strategy
They begin with background material on linear algebra and skill-building, with chapters on the basics of vectors and matrices, the framework of quantum mechanics, quibits and quantum key distribution, quantum gates and quantum circuits and their relation to quantum computing, simple quantum algorithms, quantum integral transforms, Grover's search algorithm, Shor's factorization algorithm, de-coherence, and quantum error correcting codes.
Quantum computing; from linear algebra to physical realizations by SciTech Book News
As a result, a simple quantum protocol has been successfully demonstrated, allowing controllable coupling for the execution of quantum algorithms.
