Choi Laboratory

for Ultracold Quantum Matter & Light


We are a new experimental quantum optics group led by Prof. Kyung Soo Choi in the Department of Physics & Astronomy and the Institute for Quantum Computing at the University of Waterloo. Our research focuses on the development and application of the most advanced techniques in cold atom physics and quantum optics to probe the fundamental nature of the quantum world and to investigate macroscopic quantum phenomena with strongly interacting atoms and photons near nanoscale structures. Recent developments on such systems have opened the door to an emerging field at the interface between atomic physics, condensed matter physics, and quantum information science. This new frontier utilizes genuine quantum dynamics at the level of single quanta to manipulate and examine highly entangled states of light and matter, and to build a foundation for designing new quantum optical materials at ultracold temperature.
