Our group explores the light-matter interaction and the quantum properties of light, discovering and engineering novel optical and physical functionalities.

1) Quantum optics and quantum technologies:

Our group conducts experimental research using photons. Photon is an important concept for understanding quantum phenomena such as black-body radiation and the photo-electric effect. Nowadays, photons are utilized as a tool to explore the quantum world, and expected as an essential resource (qubits) for quantum communication, quantum computing, and quantum metrology. The primary goal of our group is to gain an understanding of counter-intuitive quantum phenomena involving quantum entanglement and quantum fluctuations and to apply it to develop new quantum applications. Our research interests include nonlinear optics with single photons, observing novel multi-photon interference, generating and detecting large-scale photonic entanglement, developing optical quantum gates, and precision quantum optical measurement and networking.
