Page-Wootters状态的信息处理

Information processing with Page-Wootters states

S. Nicolis

摘要:

为了理解一个物理系统是随时间演变的,必须满足两个要求:(a)必须能够定义一个“时钟”;(b)必须能够复制系统的状态,并能够可靠地检索以进行比较。我们研究了量子力学对这些问题的约束,根据最近的实验与纠缠光子。

英文摘要:

In order to perceive that a physical system evolves in time, two requirements must be met: (a) it must be possible to define a "clock" and (b) it must be possible to make a copy of the state of the system, that can be reliably retrieved to make a comparison. We investigate what constraints quantum mechanics poses on these issues, in light of recent experiments with entangled photons.
