Title: 时间对称量子力学中的因果经典物理

Abstract: The letter submitted is an executive summary of our previous paper. To solve the Einstein Podolsky Rosen 'paradox' the two boundary quantum mechanics is taken as self consistent interpretation of quantum dynamics. The difficulty with this interpretation is to reconcile it with classical physics. To avoid macroscopic backward causation two 'corresponding transition rules' are formulated which specify needed properties of macroscopic observations and manipulations. The apparent classical causal decision tree requires to understand the classically unchosen options. They are taken to occur with an 'incomplete knowledge' of the boundary states typically in macroscopic considerations. The precise boundary conditions with given phases then select the actual measured path and this selection is mistaken to happen at the time of measurement. The apparent time direction of the decision tree originates in an assumed relative proximity to the initial state. Only the far away final state allows for classically distinct options to be selected from. Cosmologically the picture could correspond to a big bang initial and a hugely extended final state scenario. It is speculated that it might also hold for a big bang/big crunch world. If this would be the case the Born probability postulate could find a natural explanation if we coexist in the expanding and the correlated CPT conjugate contracting world. Show Chinese abstract

Abstract: 提交的信件是我们之前论文的执行摘要。 为了解决爱因斯坦波多尔斯基罗森的“悖论”，采用两种边界量子力学作为量子动力学的自洽解释。 这种解释的困难在于将其与经典物理协调起来。 为了避免宏观的逆因果性，制定了两个“对应转换规则”，这些规则指定了宏观观察和操作所需的特性。 看似经典的因果决策树需要理解经典中未被选择的选项。 它们被看作是在宏观考虑中通常对边界状态的“不完全知识”下发生的。 然后精确的边界条件在给定相位的情况下选择实际测量路径，而这种选择被误认为发生在测量时刻。 决策树的明显时间方向源于对初始状态的假设相对接近性。 只有远离的最终状态才允许从经典上不同的选项中进行选择。 从宇宙学角度看，这个图景可能对应于一个大爆炸初始状态和一个极大扩展的最终状态情景。 推测这可能也适用于一个大爆炸/大挤压世界。 如果真是这样的话，如果我们同时存在于膨胀的和相关联的CPT共轭收缩世界中，玻恩概率假说可能会找到自然的解释。
