论文摘要
我们考虑一个全球量子系统（“宇宙”）满足双重约束，无论是在总能量还是总动量上。概括页面和wootter量子时钟形式主义，我们提供了一个3+1个维，非权威性的，量子时空的模型，从全球“永恒”和“无位置”宇宙中的不同子系统之间从纠缠中浮出水面。
We consider a global quantum system (the "Universe") satisfying a double constraint, both on total energy and total momentum. Generalizing the Page and Wootters quantum clock formalism, we provide a model of 3+1 dimensional, non-relativistic, quantum spacetime emerging from entanglement among different subsystems in a globally "timeless" and "positionless" Universe.
