弯曲时空上的量子系统模型缺乏足够的实验验证。一些推测理论表明，在弯曲空间中，量子关联，如纠缠，可能表现出与纯经典关联不同的行为。通过衡量这种影响或缺乏这种影响，我们可以测试几个这样的模型背后的假设。例如，正如拉尔夫等人[]和拉尔夫和皮纳尔[]预测的那样，如果每个粒子穿过不同的引力场梯度，两粒子纠缠系统就可以在这里解码。我们建议在地面到空间上行链路的情况下研究这种影响。我们推广了拉尔夫和他的同事的上述理论预测，并讨论了探测/未能探测到所预测的引力退相干的科学后果。给出了欧洲航天局的Space Quest(空间-量子纠缠空间测试)任务的详细任务设计，并对任务方案的可行性进行了研究。
Models of quantum systems on curved space-times lack sufficient experimental verification. Some speculative theories suggest that quantum correlations, such as entanglement, may exhibit different behavior to purely classical correlations in curved space. By measuring this effect or lack thereof, we can test the hypotheses behind several such models. For instance, as predicted by Ralph et al [] and Ralph and Pienaar [], a bipartite entangled system could decohere if each particle traversed through a different gravitational field gradient. We propose to study this effect in a ground to space uplink scenario. We extend the above theoretical predictions of Ralph and coworkers and discuss the scientific consequences of detecting/failing to detect the predicted gravitational decoherence. We present a detailed mission design of the European Space Agency’s Space QUEST (Space—Quantum Entanglement Space Test) mission, and study the feasibility of the mission scheme.
