Solid-state quantum information

 

Solid-State Quantum Photonics Group

We are a newly established group aiming at controlling solid-state quantum emitters for scalable quantum information processing. The current research efforts focus on the optical control of semiconductor quantum dots for generation of high-quality, high-brightness single photons and entangled photons, solid-state test-bed of multi-photon entanglement and optical quantum computing, spin-photon quantum interface, and hybrid quantum networks.

We always look forward to hearing from you: highly-motivated PhD students and post-doctoral fellows.
