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…

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…

Two-level system hyperpolarization using a quantum Szilard engine
Martin Spiecker, Patrick Paluch, Nicolas Gosling +16
The innate complexity of solid state physics exposes superconducting quantum circuits to interactions with uncontrolled degrees of freedom degrading their coherence. By using a sim…
