论文摘要
量子信息实验在外层空间应用量子光学的实验具有很长的基线可能比当前的地球结合实验或地球到卫星实验具有优势，因为它们可以最大程度地减少光传输的损失并最大程度地分辨时间分辨率。这一未来的实验类别（其中包括量子传送和纠缠交换）可以阐明重力量子物理学和相对论量子信息的许多基本理论问题。关于相对论理论，在外部空间设置中的这些实验可能涉及观察者在空间和时机分离上，并从不同的时间切片选择中阐明了有趣的现象。关于量子信息，它们可能能够确保贝尔测试中期望值的因果独立性。本文通过分析和解释解决了这些问题。
Quantum information experiments applying quantum optics in outer space with a very long baseline may have advantages over the current earth-bound experiments or the earth-to-satellite experiments because they can minimize the loss in light transmission and maximize the gain in time resolution. This future class of experiments, amongst them quantum teleportation and entanglement swapping, can shed light on many fundamental theoretical issues in gravitational quantum physics and relativistic quantum information. Regarding relativity theory, these experiments in an outer-space setting can involve observers at spacelike and timelike separations and explicate intriguing phenomena from different choices of time-slicing. Regarding quantum information, they may be able to ensure the causal independence of the expectation values in the Bell test. These issues are addressed in this paper with analysis and explanations.
