论文摘要
在量子计量学中,通常会在原子或光子之间产生相关性,以增强测量精度。在这里,我们展示了如何以旋转轨道耦合的Bose-Einstein冷凝物和库仑晶体的质量中心激发和库仑晶体进行量子增强测量。我们还提出了一种模拟这些系统中质量激发的同伴检测的方法,这是最佳估计所必需的。
In quantum metrology, one typically creates correlations among atoms or photons to enhance measurement precision. Here, we show how one can use other excitations to perform quantum-enhanced measurements on the example of center-of-mass excitations of a spin-orbit coupled Bose-Einstein condensate and a Coulomb crystal. We also present a method to simulate a homodyne detection of center-of-mass excitations in these systems, which is required for optimal estimation.
