Ultracold Atoms and Nanophotonics Laboratory

 

Welcome to the laboratory for ultracold atoms and nanophotonics at Purdue University. We explore fascinating quantum phenomena in atomic, molecular, and optical systems using state-of-the-art quantum control and measurement techniques, as well as nanophotonics atom-light interfaces. By cooling ultracold gases to their quantum ground states, we aim to build versatile quantum machines that operate under the principles of quantum mechanics. Our research focuses on studying their quantum and thermodynamic behaviors and discovering innovative applications in quantum science and engineering.
