论文摘要
作为Arxiv的扩展：\ {2002.02448，2008.10740 \}我们提供了一个物理协议，当一组观察者可以使用该协议来检测纯状态，当它们散布在$ \ natercal {i}^+_- $的小空间中时，它们会散布在$ \ Mathcal {i}^+_- $中。该协议涉及使用简单的单一操作员修改散装状态以及对国家能量的测量。我们研究的状态是通过与低能运营商在真空状态下作用的，使得扰动分析是有效的。我们将自己限制在$ 3+1 $的空间上，只考虑无数的激励。从该分析中，在渐近平坦的时空中，信息全息原理显现出来。
As an extension of arXiv:\{2002.02448, 2008.10740\} we present a physical protocol that a set of observers can use to detect a pure state in the bulk when they are spread across a small cut near $\mathcal{I}^+_-$ in flat spacetime. The protocol involves the modification of a bulk state using simple unitary operators and measurements of the energy of the state. The states that we study are constructed by acting with low energy operators on a vacuum state such that a perturbative analysis is valid. We restrict ourselves to $3+1$ dimensional spacetimes and only consider massless excitations. From this analysis, the principle of holography of information becomes manifest in the case of asymptotically flat spacetime.
