论文摘要
我们回顾了量子力学的蒙得维的诺解释，该解释是基于使用真实时钟来描述物理学的，使用了Hoehn，Smith和Lock最近引入的框架来处理一般协变的系统中的时间问题。新的形式主义的使用使读者更容易进入整个构造，而又不熟悉完全受约束的系统。我们发现，就像原始的表述一样，出现了磨损的基本机制，它允许补充普通的环境腐烂并避免其批评。量子复杂性的最新结果为用于证明在普通的 - 单一 - 量子力学中没有确定的事件的全局方案类型提供了额外的支持。代替这一点，以可能的结果的连贯叠加开始的说法始终是叠加。我们表明，如果人们考虑了由于总体相对论和量子力学而导致的长度和时间间隔的基本不可避免的不确定性，那么前面提到的全局协议将不再允许区分状态是否处于叠加位置。一个纯粹用量子力学定义的量子力学的表述，而没有任何参考经典世界，并且具有不需要外部观察者的量子事件的内在操作定义。
We review the Montevideo Interpretation of quantum mechanics, which is based on the use of real clocks to describe physics, using the framework recently introduced by Hoehn, Smith and Lock to treat the problem of time in generally covariant systems. The use of the new formalism makes the whole construction more accessible to readers without familiarity with totally constrained systems. We find that as in the original formulation, a fundamental mechanism of decoherence emerges that allows to supplement ordinary environmental decoherence and avoid its criticisms. Recent results on quantum complexity provide additional support to the type of global protocols used to prove that within ordinary -- unitary -- quantum mechanics no definite event -- an outcome to which a probability can be associated -- occurs. In lieu of this, states that start in a coherent superposition of possible outcomes always remain as a superposition. We show that, if one takes into account fundamental inescapable uncertainties in measuring length and time intervals due to general relativity and quantum mechanics, the previously mentioned global protocols no longer allow to distinguish whether the state is in a superposition or not. One is left with a formulation of quantum mechanics purely defined in quantum mechanical terms without any reference to the classical world and with an intrinsic operational definition of quantum events that does not need external observers.
