LL Lab explores how light and cold atoms interact, with a focus on quantum many-body physics. Our platform combines control over individual atoms with the collective coupling provided by an optical cavity. We use these capabilities to study quantum measurement and many-body entanglement, and to develop approaches to quantum computing and precision sensing.

In our lab, we use ultracold atoms to perform quantum simulations and explore the rich physics of low-dimensional quantum gases and strongly correlated many-body systems. In low dimensions, restricted particle motion allows interactions and quantum fluctuations to give rise to collective behavior distinct from that in three-dimensional systems. By building a highly controllable experimental platform, we aim to understand how microscopic interactions determine macroscopic properties, and how an isolated quantum many-body system approaches equilibrium or retains memory of its initial state over long times.

In our lab, we focus on controlling the interaction between ultracold atoms, which is the origin of almost all many-body phenomena and a powerful tool in both fundamental researches and quantum simulations.

Our laboratory explores quantum computing and quantum many-body physics using programmable arrays of neutral atoms. By trapping individual atoms in optical tweezers and controlling their internal states with laser light, we build quantum systems whose geometry and interactions can be tailored to different research questions. Strong interactions between atoms excited to Rydberg states enable both entangling quantum gates and the study of collective quantum behavior.

“Baize,” our quantum computing experimental platform powered by AI agents, enables closed-loop execution driven by human natural language instructions, as well as autonomous correction and predictive maintenance of key quantum computing metrics. Our project accelerates the engineering and industrialization of practical quantum computing.
