Exploring new degrees of freedom in optical quantum materials
The State Key Laboratory of Optical Quantum Materials brings together photonics and two-dimensional materials to develop quantum materials and metamaterials. Focusing on ultrafast processes and topological structures, the Laboratory supports technological innovation in the Guangdong–Hong Kong–Macao Greater Bay Area.
With light–matter interactions at its core, the Laboratory connects photon physics, low-dimensional condensed-matter physics, micro- and nanoscale device physics, and information science to explore the control and interconversion of multiple photonic and electronic quantum degrees of freedom.
Establishing the fundamental physics foundations for next-generation information technologies.
