Purdue Science

Welcome to the laboratory for ultracold atomic physics and quantum optics at Purdue University, where we are exploring facinating quantum phenomena in atomic, molecular, and optical systems with state-of-the-art quantum control and measurement techniques. Using ultracold gases cooled to their quantum ground states, we aim at building generic quantum machines that follow well-controlled actions and rules of quantum mechanics, and studying their quantum-/thermo-dynamics. We hope to provide new perspectives to research frontiers in few- and many-body physics.
