Quantum simulation and computation with programmable Rydberg atom arrays
Abstract. Rydberg atom arrays have emerged in the past few years as a promising resource for quantum simulation and quantum information processing. The ability to produce arbitrary spatial arrangements of neutral atoms is combined with the coherent control of their internal states, including coupling to Rydberg states to achieve strong interactions, to create an extremely versatile platform. Recent experiments on 1D arrays have highlighted the potential of this system for high-fidelity quantum information processing, demonstrating two different techniques for entanglement engineering. I will present these results and report on the recent upgrade of our platform to control hundreds of atoms in arbitrary 2D geometries.

Entanglement-enhanced interferometry with neutral atoms
Abstract. Precision measurement and inertial sensing applications have relied on neutral atoms for many years. Recent advancements in utilizing Rydberg dressing to mediate strong, tunable interactions between neutral alkali atoms suggest that neutral atoms now also provide a promising platform for quantum sensing. Members of our team have shown that entanglement can enhance the performance of an atom interferometer, since the measurement uncertainty will follow Heisenberg scaling. Following a recent demonstration of entanglement of two Cs atoms in optical dipole traps and building on expertise in atom interferometry, we report on progress toward implementation of an entanglement-enhanced atom interferometer, which has the capability to scale to many atoms in the current apparatus. We discuss the effects of various error sources on the fidelity and progress on overcoming critical experimental challenges, as we work towards making advanced quantum sensing with neutral atoms a reality.
