标题： Individual assembly of two-species Rydberg molecules using optical tweezers

摘要： 我们提出了一种新的研究Rydberg分子的方法，通过使用光学镊子展示和表征单个Rb$^{*}$Cs Rydberg分子的形成和特性。 通过采用单原子检测的Rb和Cs，我们通过两种物种的关联损失观察分子的形成，并以单粒子分辨率研究形成动力学。 我们通过操纵原子对的相对波函数来控制原子间距离，利用镊子强度优化与分子态的耦合，并探索镊子对这些态的影响。 此外，我们展示了在不同镊子中捕获的原子之间的分子结合，为多原子分子的状态选择性组装铺平了道路。 观测到的结合能、分子取向和键长与理论结果相符。 我们的方法广泛适用于Rydberg镊子平台，扩展了可用分子系统的范围，并使Rydberg分子集成到现有的量子科学平台成为可能。 显示英文摘要

摘要： We present a new approach to investigating Rydberg molecules by demonstrating the formation and characterization of individual Rb$^{*}$Cs Rydberg molecules using optical tweezers. By employing single-atom detection of Rb and Cs, we observe molecule formation via correlated loss of both species and study the formation dynamics with single-particle resolution. We control the interatomic distances by manipulating the relative wavefunction of atom pairs using the tweezer intensity, optimizing the coupling to molecular states and exploring the effect of the tweezer on these states. Additionally, we demonstrate molecule association with atoms trapped in separate tweezers, paving the way for state-selective assembly of polyatomic molecules. The observed binding energies, molecular alignment, and bond lengths are in good agreement with theory. Our approach is broadly applicable to Rydberg tweezer platforms, expanding the range of available molecular systems and enabling the integration of Rydberg molecules into existing quantum science platforms.
