论文摘要
我们研究了加速度对双孔状态的影响，该状态是一类特定的多体纠缠量子状态，并且已经以高精度和灵敏度在实验上实现。我们表明，多体量子纠缠可以随着加速度而增加，这与“抗unruh效应”一致，因为它参考了以前指出的违反直觉冷却，以耦合与真空的加速检测器。特别是，这种纠缠增加会导致相位灵敏度的提高，这提供了一种在将来实验中测试抗UNRUH效应的方法。
We study the influence of acceleration on the twin-Fock state which is a class of specific multibody entangled quantum state and was already realized experimentally with high precision and sensitivity. We show that the multi-body quantum entanglement can be increased with the acceleration, consistent with the "anti-Unruh effect" in reference to the counterintuitive cooling previously pointed out for an accelerated detector coupled to the vacuum. In particular, this kind of entanglement increase can lead to the improvement of the phase sensitivity, which provides a way to test the anti-Unruh effect in the future experiments.
