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.
