Quantum Measurement and Quantum Computation
The measurement problem which is one of the controversial problems of quantum mechanics is presented, the collapse theory and the no-collapse theory are illustrated respectively and the rationality of the two theories is stated by drawing a comparison between them.
Abstract
This paper mainly discusses the measurement in quantum mechanics. At first,it starts from the postulates of quantum mechanics and the meaning of measurement postulate is mainly analyzed. Secondly, the measurement problem which is one of the controversial problems of quantum mechanics is presented. Then the collapse theory and the no-collapse theory are illustrated respectively and the rationality of the two theories is stated by drawing a comparison between them. And then the discussion of simultaneous measurement is presented. Finally, representations of measurement in several virtual hardware models are briefly described and also the problems that measurement brings about are considered.
