标题： Optimal squeezing for high-precision atom interferometers

摘要： 我们证明，压缩是基于超冷相互作用物质的空间分离的干涉仪的关键资源。原子相互作用导致这些原子干涉仪的精度存在普遍限制，这种限制既不能通过增加原子数量，也不能通过传统的相位或数目的压缩来超越。然而，量身定制的压缩态可以通过预见由相互作用引起的最主要有害效应来克服这一灵敏度极限。我们设想其在未来的高精度差分物质波干涉仪中的应用，特别是梯度计，例如用于引力波探测。 显示英文摘要

摘要： We show that squeezing is a crucial resource for interferometers based on the spatial separation of ultra-cold interacting matter. Atomic interactions lead to a general limitation for the precision of these atom interferometers, which can neither be surpassed by larger atom numbers nor by conventional phase or number squeezing. However, tailored squeezed states allow to overcome this sensitivity bound by anticipating the major detrimental effect that arises from the interactions. We envisage applications in future high-precision differential matter-wave interferometers, in particular gradiometers, e.g., for gravitational-wave detection.
