论文摘要
我们在扩展的Fock空间中提出了量子力学的表述，其中将张量的产品结构应用于时间。与特定理论的动力学一致的历史子空间由相应的经典作用的直接量子泛化来定义。这种量子作用的对角化使我们能够恢复常规量子力学的预测，并揭示了所有物理理论之间的统一等效性。量子相关性和跨时间和不同理论之间的相干效应获得了严格的含义，该含义是在物理状态的丰富时间结构中编码的。与现代相对论方案的联系以及路径积分配方也出现了。
We propose a formulation of quantum mechanics in an extended Fock space in which a tensor product structure is applied to time. Subspaces of histories consistent with the dynamics of a particular theory are defined by a direct quantum generalization of the corresponding classical action. The diagonalization of such quantum actions enables us to recover the predictions of conventional quantum mechanics and reveals an extended unitary equivalence between all physical theories. Quantum correlations and coherent effects across time and between distinct theories acquire a rigorous meaning, which is encoded in the rich temporal structure of physical states. Connections with modern relativistic schemes and the path integral formulation also emerge.
