Abstract
In this talk, I will discuss our pathway toward quantum simulations and computation with neutral atoms in arrays of optical tweezers cooled to their motional ground state. Initially, I will talk about two-atom interference experiments, e.g. the atomic analog to the Hong-Ou-Mandel effect, and how we create spin entangled states. I will then talk about how we scale our system to accommodate 80 single atoms, loaded into 100 traps while maintaining full single-atom control. For this efficient loading process, we control atomic collisions in the tweezers using grey molasses. When combined with ground-state cooling and atom-rearranging, this should allow us to form a micro-BEC with controlled atom number and entropy.
