我们提出了一个实验来测试重力和加速度对天基装置中量子纠缠的影响。我们发现，两个玻色-爱因斯坦凝聚体的激发之间的纠缠退化后，其中一个经历了引力场强度的变化。如果凝聚物最初在处于同一轨道的两颗独立卫星上纠缠，然后其中一颗卫星移动到不同的轨道，则可以检验这一预测。我们表明，在典型的轨道机动的纳米卫星，如CanX 4和CanX 5的效果是可以观察到的。
We propose an experiment to test the effects of gravity and acceleration on quantum entanglement in space-based setups. We show that the entanglement between excitations of two Bose-Einstein condensates is degraded after one of them undergoes a change in the gravitational field strength. This prediction can be tested if the condensates are initially entangled in two separate satellites while being in the same orbit and then one of them moves to a different orbit. We show that the effect is observable in a typical orbital manoeuvre of nanosatellites like CanX4 and CanX5.
