论文摘要
据信，对重力的明确量子标志的实验观察被认为是当前技术的掌握。然而，最近的一些有前途的提案来测试重力的非古典特征似乎可以通过最先进的桌面实验来访问。其中，有些旨在测量两个肿块之间的重力诱导的纠缠，这将是重力的独特的非经典特征。我们通过监测相应的纠缠程度，在其中两个提案中明确研究了变质对系统动力学的影响。我们确定成功执行实验所需的实验条件。同时，我们还解释了连续自发定位（CSL）模型的可能影响，这是自发波函数崩溃模型中最著名的。我们发现，CSL模型参数的任何值都将完全阻碍重力引起的纠缠的产生。
The experimental observation of a clear quantum signature of gravity is believed to be out of the grasp of current technology. However, several recent promising proposals to test the possible existence of non-classical features of gravity seem to be accessible by the state-of-art table-top experiments. Among them, some aim at measuring the gravitationally induced entanglement between two masses which would be a distinct non-classical signature of gravity. We explicitly study, in two of these proposals, the effects of decoherence on the system's dynamics by monitoring the corresponding degree of entanglement. We identify the required experimental conditions necessary to perform successfully the experiments. In parallel, we account also for the possible effects of the Continuous Spontaneous Localization (CSL) model, which is the most known among the models of spontaneous wavefunction collapse. We find that any value of the parameters of the CSL model would completely hinder the generation of gravitationally induced entanglement.
