Open system quantum simulation with Rydberg atoms

利用多粒子量子系统的非经典特性是量子模拟、量子通信或量子增强测量等破坏性量子技术的核心。最近，PI和其他人发现，受控耗散可以是实现这些未来应用的宝贵资源。然而，耗散量子多体系统远离热平衡，因此与其平衡对应物非常不同，需要新的理论工具和概念来研究它们。本研究计划的目标是进一步推进PI开创的耗散系统动力学的一种新的变分方法，并将这种方法应用于强相互作用的Rydberg原子。特别是，耗散里德伯气体作为一个理想的环境，研究耗散量子多体动力学，由于其无与伦比的相互作用和耗散属性。在这个框架内，对耗散量子多体系统的新的基本见解是触手可及的，以及为正在进行的和未来的实验提供第一个从头算模拟。

Harnessing non-classical properties of many-particle Quantum systems lies at the heart of disruptive quantum technologies such as quantum simulation, quantum communication, or quantum-enhanced measurements. Recently, the PI and others have discovered that controlled dissipation can be a valuable resource in enabling These future applications. However, dissipative quantum many-body systems are far away from thermal equilibrium and therefore behavevery differently from their equilibrium counterparts, requiring new theoretical tools and concepts to study them. The goal of this research proposal is to further advance a novel variational Approach to the dynamics of dissipative systems, which has been pioneered bythe PI, and to apply this method to strongly interacting Rydberg atoms. In particular, dissipative Rydberg gases serve as an ideal environment to study dissipative quantum many-body dynamics, thanks to their unrivaled interaction and dissipation properties. Withinthis framework, new fundamental insights into dissipative Quantum many-body systems are within reach, as well as providing the first abinitio simulations for ongoing and future experiments.
