Means of controlling the internal and motional states of neutral atoms allow us to create novel quantum systems with enormous flexibility. These atomic systems serve as a play-space to explore current topics in quantum science. I will highlight this development by providing examples from my research group’s work. In particular, I will show how ultracold atoms placed at the intersection of several laser beams can probe geometric aspects of band structure in new ways. I will show how real-time measurements on quantum systems can shed light on non-equilibrium thermodynamics in mesoscopic systems. I will also show how single atoms can be used as single-quantum sensors in a scanning-probe microscope. Finally, I will share some ideas on how ultracold atoms can play a role in quantum computing, and describe Berkeley’s new Challenge Institute for Quantum Computing as a home for such work.
