2026/01/10 | I will be leaving NUS-CQT in February and joining the Institute of Quantum Physics, School of Physics, Central South University, as a specially appointed Associate Professor. I will establish a research group focused on interdisciplinary work at the intersection of quantum information, quantum matter, and quantum field theory. More details will be updated later. Welcome to join the group.
