Welcome to the Asenjo-Garcia research group at Columbia University.

Our group’s research focus is on theoretical quantum optics and its intersection with quantum information science and many-body physics. We are interested in understanding the emergence of order and self-organization in far-from equilibrium open quantum systems. We harness this understanding to develop novel protocols for quantum information storage and processing, non-linear quantum optics, and metrology.
