SUMMARY:Workshop / Seminar:CM-AMO Seminar | Tailoring Rydberg interactions for expanding quantum capabilities
DESCRIPTION:Rydberg atoms provide a uniquely versatile platform for engineering strong\, tunable interactions in otherwise weakly interacting neutral-atom systems. They couple strongly to each other and to external fields. The former enables controllable atom-atom\, atom-photon and even photon-photon interactions\, while the latter promises exceptionally sensitive and broadband microwave (MW) and radio frequency (RF) sensing capabilities. Typically\, the Rydberg-Rydberg interactions are leveraged as a blockade mechanism. In contrast\, we explore the antiblockade regime in atom arrays\, where interactions facilitate rather than suppress excitation. I will present our numerical studies demonstrating directional quantum information and entanglement transfer [1]\, as well as robust avalanche amplification for weak signal detection [2]. For atom-field coupling\, I will present our experimental work expanding MW sensing capabilities with cold atomic ensembles. First\, we demonstrate 3D field characterization via multi-parameter extraction\, which holds potential as a testbed for machine-learning-enhanced measurement protocols and has broad implications for information extraction from complex measurements. Second\, we address the intersection of atom-atom and atom-field interactions by investigating the role of nonlinear atomic interactions in probing external fields [3]. Together\, these studies show how tailoring Rydberg interactions expands the accessible measurement and dynamical capabilities of cold-atom platforms.\n \nReferences:\n[1] Yupeng Wang\, Junjie Wang\, Aishik Panja\, Xinghan Wang\, Qi-Yu Liang\, “Directional Transport in Rydberg Atom Arrays via Kinetic Constraints and Temporal Modulation”\, Phys.
