quantum computer
quantum computern. A computer that exploits the quantum mechanical properties of subatomic particles to allow a single operation to act on a large amount of data.quantum computer n (Computer Science) a type of computer which uses the ability of quantum systems to be in many different states at once, thus allowing it to perform many different computations simultaneously
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. quantum computer (computer)A type of computer which uses the ability ofquantum systems, such as a collection of atoms, to be in manydifferent states at once. In theory, such superpositionsallow the computer to perform many different computationssimultaneously. This capability is combined with interferenceamong the states to produce answers to some problems, such asfactoring integers, much more rapidly than is possible withconventional computers. In practice, such machines have notyet been built due to their extreme sensitivity to noise.
