| Abstract: | Microscopic detection and control of ensembles of neutral atoms have transformed our ability to study and create complex many-body systems. Techniques like quantum gas microscopy and optical tweezers grant a new single-particle-resolved perspective on solid-state analogs and idealized quantum spin models, as well as altogether novel detection capabilities for fundamentally quantum quantities like entanglement. In this talk, I will describe our group's progress towards developing these tools for a new atomic species, strontium. The rich internal space of such two-electron atoms enables a variety of avenues -- frustrated magnetism, quantum information processing with nuclear qubits, new gate architectures, to name a few-- that each stand to benefit from a microscopy-enabled toolset. Importantly, our recent work also demonstrates a new direction for these tools of microscopic control -- neutral-atom optical clocks -- a marriage which has a number of strengths for metrology. To this end, I will report our recent results of seconds-scale atom-optical coherence, which are directed towards the development of a high-duty cycle tweezer-array clock. I will further describe our plans to incorporate Rydberg-dressing into this platform, in order to create entangled states of enhanced metrological sensitivity. | |
