Deep Reinforcement Learning for Individual Atomic Control and Cooling
Matthew L. Peters, Guoqing Wang, David C. Spierings +5
Real-time feedback control of quantum systems is often limited by partial observations, nonlinear dynamics and measurement noise, which make accurate model-based controllers diffic…

Programmable few-atom Bragg scattering and ground-state cooling in a cavity
Guoqing Wang, David C. Spierings, Matthew L. Peters +3
By integrating tweezer arrays with a high-cooperativity ring cavity with chiral atom-cavity coupling, we demonstrate highly directional Bragg scattering from a programmable number…

Cavity-enabled real-time observation of individual atomic collisions
Matthew L. Peters, Guoqing Wang, David C. Spierings +4
Using the strong dispersive coupling to a high-cooperativity cavity, we demonstrate fast and non-destructive number-resolved detection of atoms in optical tweezers. We observe indi…
