论文摘要
一种简单的方法，即本科生可以访问的，以了解量子力学中的测量值。量子力学的整体解释是自然的，可以简单地访问测量问题。本文解释了这种相对年轻的解释的测量，最初是由L. ballentine从1970年代开始严格的。通过使用严格的Gerlach实验对Wigner Friend参数的详细说明来证明其设施。在最近的教科书之后，通过分析自由粒子状态以及Schrodinger Cat悖论，进一步开发了这种方法。哥本哈根解释的某些陷阱被抽出了。
A simple way, accessible to undergraduates, is given to understand measurements in quantum mechanics. The ensemble interpretation of quantum mechanics is natural and provides this simple access to the measurement problem. This paper explains measurement in terms of this relatively young interpretation, first made rigorous by L. Ballentine starting in the 1970's. Its facility is demonstrated through a detailed explication of the Wigner Friend argument using the Stern Gerlach experiment. Following a recent textbook, this approach is developed further through analysis of free particle states as well as the Schrodinger cat paradox. Some pitfalls of the Copenhagen interpretation are drawn out.
