论文摘要
我们提出了一项新协议，用于在可控的原子，分子和光学系统中准备旋转挤压状态，并与与Rydberg Itsportions兼容的新兴光学时钟平台特别相关。通过将短距离的软核电势与外部驱动器相结合，我们可以在打开多体间隙的同时将自然新兴的Ising Ising Isstions转换为XX自旋模型。该差距有助于将系统维持在状态的集体歧管中，在该状态下，可以在具有真正的全能相互作用的系统中生成的旋转挤压水平生成量子挤压。我们研究了我们的方案的鲁棒性，即实验相关的破裂性，并表现出比缺乏差距保护的典型协议表现出的良好性能。
We propose a new protocol for preparing spin squeezed states in controllable atomic, molecular, and optical systems, with particular relevance to emerging optical clock platforms compatible with Rydberg interactions. By combining a short-ranged, soft-core potential with an external drive, we can transform naturally emerging Ising interactions into an XX spin model while opening a many-body gap. The gap helps maintain the system within a collective manifold of states where metrologically useful spin squeezing can be generated at a level comparable to the spin squeezing generated in systems with genuine all-to-all interactions. We examine the robustness of our protocol to experimentally-relevant decoherence and show favorable performance over typical protocols lacking gap protection.
