论文摘要
从理论上讲，我们研究了使用量子非解析测量的使用，以增强原子干涉测量法与玻色符合原子的敏感性。特别是，我们关注的是增强现有的高精度原子干涉仪，因此将自己限制在稀释原子样本中，以及在弱耦合方面中使用自由传播光或光腔。我们发现最佳参数是平衡自旋挤压和原子损失之间的最佳参数，并发现灵敏度可以显着提高。最后，我们考虑使用挤压光的使用，并表明这可以为灵敏度提供进一步的增强。
We theoretically investigate the use of quantum non-demolition measurement to enhance the sensitivity of atom interferometry with Bose-condensed atoms. In particular, we are concerned with enhancing existing high-precision atom interferometry apparatuses, so restrict ourselves to dilute atomic samples, and the use of free-propagating light, or optical cavities in the weak-coupling regime. We find the optimum parameter regime that balances between spin squeezing and atomic loss, and find that significant improvements in sensitivity are possible. Finally, we consider the use of squeezed light, and show that this can provide further boosts to sensitivity.
