Research Interests and achievement

Our research is focused on generating single and entangled photons and manipulating the photon-matter interaction. Single photons are wavepackets of light energy quanta and no-cloning property. Entangled photons, on the other hand, are photon pairs with “spooky action at a distance” quoted by Einstein. With unique quantum properties, they are both essential to realizing quantum computation, quantum communication, and quantum teleportation, and to understanding quantum mechanics.

We seek to develop applications with single and entangled photons and to study the analogue between the photonic system and other physical systems by manipulating their quantum property. We use optical methods and lasers in experiments and build theoretical models to explain our observations. Our material systems include solid-state, semiconductor, or cold atom systems. This research area leads to applications as well as fundamental interests.
