Summary

In this lecture, Ana Maria Rey discusses the potential of ultracold atoms in optical cavities for quantum simulation and sensing. She begins by outlining key challenges in quantum many-body physics, such as cooling, fast entanglement generation, scalability, and dissipation. She explains how cavity-mediated interactions, which are infinite-range, can overcome these challenges. The lecture details an experimental setup using rubidium atoms in a high-finesse cavity, where momentum states are used as effective spins. She derives the effective Hamiltonian, which features one-axis twisting and exchange interactions. She then discusses how to engineer Hamiltonians beyond the standard paradigm, including multi-body interactions, to accelerate entanglement generation. She also touches on using multi-level atoms (qudits) to enhance scalability. The talk emphasizes the collaborative theory-experiment approach and highlights record-level spin squeezing achieved via cavity QED.
