量子理论与时间不对称

Quantum Theory and Time Asymmetry

H. D. Zeh

摘要:

研究了量子测量与热力学不可逆过程的关系。状态向量的约简在时间上是基本上不对称的,并且显示出一种与时间相关的关系,这可以解释状态向量作为物理状态的表示以及关于它们的信息的双重解释。不可逆热力学的所有统计理论中使用的相关性的概念被证明是基于相同的不可逆相关性。不可逆过程的量子理论隐含地使用了状态矢量归约的客观化过程。条件的减少进行了讨论,我推测,最终的(主观)观察者系统甚至可能是由一个时空点。

英文摘要:

The relation between quantum measurement and thermodynamically irreversible processes is investigated. The reduction of the state vector is fundamentally asymmetric in time and shows an observer-relatedness which may explain the double interpretation of the state vector as a representation of physical states as well as of information about them. The concept of relevance being used in all statistical theories of irreversible thermodynamics is shown to be based on the same observer-relatedness. Quantum theories of irreversible processes implicitly use an objectivized process of state vector reduction. The conditions for the reduction are discussed, and I speculate that the final (subjective) observer system might even be carried by a spacetime point.
