Event Details & Abstracts

Quantum systems built using atoms and light are expected to revolutionize the way we sense and measure properties of our universe. In this talk, I will report on theoretical efforts aimed at advancing the capabilities of atomic platforms for quantum metrology. First, I will briefly discuss the modeling of an experiment that has succeeded in near ground-state cooling large trapped ion crystals in a Penning trap. Second, I will summarize a new readout technique using atom-cavity interactions, that can continuously and precisely track the relative phase of a spin superposition. Finally, I will detail a scheme to engineer spin squeezing in atomic Bragg interferometers, a sensing platform that has traditionally relied on single-atom physics for its operation.
