Trey Porto: Coherent control of neutral atoms in optical lattices

Trey Porto, National Institute of Standards and Technology

Abstract

Experiments with ultra-cold atoms lie at the intersection of precision atomic physics, quantum information and many-body physics. I will give an overview of experiments at NIST demonstrating coherent control of atoms trapped in optical lattices. We use a dynamically controllable bi-partite lattice to control the motional and spin degrees of freedom of 87Rb atoms with high fidelity, with the ability to address atoms in sub-lattices. Our approach has applications for the study quantum many-body physics and for using cold atoms as a platform for quantum information processing. I will discuss past experiments and future directions.
