摘要
本文的讨论主要集中在量子力学中测量部分,首先从量子力学的几大公设出发,着重分析测量公设的含义。然后提出量子力学争论的焦点问题之一——测量问题,并通过分别阐述塌缩原理、非塌缩原理以及对二者的比较来分析各种说法的合理性。接下来简要讨论同时测量问题。最后简略描述测量在不同量子计算模型中的体现,并对测量带来的问题做了思考。
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.
