论文摘要
介导两个量子系统之间的纠缠的领域必须具有量子性质。最近，通过桌面实验进行了积极研究，试图通过这种方式目睹这种方式的引力场的量子样特征，尤其是通过考虑在两个位置的叠加中查看两个质量，每个质量都在两个位置中，每个质量都在一个干涉仪中。当并排放置干涉仪时，探测纠缠干预措施。如果质量仅通过牛顿吸引力相互作用，并且仍然发现某种程度的纠缠，那么重力场必须是量子，至少是非古典的。所考虑的质量是介观，10-14 kg至10-12 kg，在一个提案中，考虑了马赫德尔干涉法。液体HE4在2.17 K以下是超氟，并且显示出宏观的量子行为，特别是物质干涉法，例如在超氟He量子内部的量子内部设备-Shequid中。 Shequid凭借其约瑟夫森（Josephson）的连接处作为缝隙，与Mach-Zhhnder相似。在这种情况下，所涉及的量为宏观，10-8 kg。我们建议并分析方案在上述线上的可行性，在上面的线路上，超级流体HE4给出了物质字段，而Mach-Zehnder的则是两个shequid，并排放置。我们发现，仅使用经过良好证明的方法和技术，提出的实验是可行的，而无需扩展到当前边界之外。
A field, which mediates entanglement between two quantum systems, must be of quantum nature. Attempts to witness this way quantumlike features of the gravitational field with tabletop experiments are actively studied recently, in particular by considering to look at two masses in a superposition in two locations, each in one interferometer. Entanglement intervention is probed when the interferometers are put side by side. If the masses interact only via Newtonian attraction, and still some degree of entanglement is found, than the gravitational field must be quantum like, or at least non-classical. The masses considered are mesoscopic, 10-14 Kg to 10-12 Kg, and in one proposal Mach-Zehnder interferometry is considered. Liquid He4 is superfluid below 2.17 K, and shows macroscopic quantum behaviour, in particular matter interferometry, as in the Superfluid He Quantum Inteference Device - SHeQUID. With its Josephson junctions as slits, the SHeQUID parallels a Mach-Zehnder. In this case the matter quantities involved are macroscopic, 10-8 Kg. We propose and analize the feasibility of a scheme on the lines of the above, where the matter field is given by superfluid He4, and the Mach-Zehnder's are two SHeQUID, put side by side. We find that the proposed experiment is feasible, using only well demonstrated methods and technologies, with no need to extensions beyond the current frontiers.
