Reconfigurable Optical Tweezer Arrays of CaF Molecules for Quantum Simulation

When
-

Reconfigurable molecular tweezer arrays are a new emerging platform for quantum science. In recent years, significant progress has been made in controlling molecules and developing essential building blocks for quantum simulation and quantum information processing. In this talk, I will present our work on CaF molecular tweezer arrays. Specifically, I will first discuss the observation of coherent spin exchange oscillations between pairs of molecules and creation of Bell states.

Dirac spin liquid in dipolar Rydberg arrays

When

Abstract: Pull an atom's electron far (~100 nm) from its nucleus, and you will get a large electric dipole. In this talk, I will discuss what can happen if you do this to 100+ atoms trapped in an optical tweezer array, where the dipole-dipole interactions manifest as a long-range spin-1/2 XY model. My focus will be on the ensuing many-body ground state physics: on the kagome lattice, numerical calculations indicate this dipolar XY model naturally yields a gapless Dirac spin liquid.
