量子力学中的测量问题与满射假说

Measurement Problem in Quantum Mechanics and the Surjection Hypothesis

Fritz W. Bopp

摘要:

从幺正量子动力学开始,我们研究如何加入量子测量。量子测量有四个基本组成部分:分叉、见证产生、对准投影和实际选择决定。前两个分量仍然属于幺正量子动力学的范畴。退相干概念解释了第三个贡献。它可以基于这样的要求,即在波函数侧和共轭侧到达时间终点的见证必须相同。这样,它也停留在量子动力学领域内。满射假说解释了实际的选择决策。它是基于应用于完整量子宇宙的双边界解释。它提供了一种简单的方法,将这些看似随机的投影简化为纯粹确定性的幺正量子动力学,消除了测量问题。

英文摘要:

Starting with unitary quantum dynamics, we investigate how to add quantum measurements. Quantum measurements have four essential components: the furcation, the witness production, an alignment projection, and the actual choice decision. The first two components still lie in the domain of unitary quantum dynamics. The decoherence concept explains the third contribution. It can be based on the requirement that witnesses reaching the end of time on the wave function side and the conjugate one have to be identical. In this way, it also stays within the quantum dynamics domain. The surjection hypothesis explains the actual choice decision. It is based on a two boundary interpretation applied to the complete quantum universe. It offers a simple way to reduce these seemingly random projections to purely deterministic unitary quantum dynamics, eliminating the measurement problem.
