Adam Kaufman will describe two experimental platforms --- optical tweezer trapping of single atoms and quantum gas microscopy --- and how they have been used to realize experiments with low-entropy systems of neutral atoms. While these platforms share a common goal of creating and microscopically manipulating quantum states of neutral atoms, they employ opposite strategies. The optical tweezer approach aims to assemble quantum systems from single atoms in a bottom-up fashion; quantum gas microscopes employ a top-down strategy, where smaller many-body systems are distilled from larger samples. In describing these ideas, Adam Kaufman will focus on two experiments he and his team performed that utilize the capabilities of these platforms. In one experiment with optical tweezers, they realized atomic Hong-Ou-Mandel interference with independently prepared atoms. In a second experiment with a quantum gas microscope, they performed studies of quantum thermalization, which leverage this atomic Hong-Ou-Mandel interference to probe the role of entanglement in thermalization of closed systems. Lastly, Adam Kaufman will discuss future avenues that draw on the capabilities of these platforms and build on these experimental studies.
