Nanophotonic Cavity Quantum Electrodynamics Research Team Team Leader
Outline
Our research team study cavity quantum electrodynamics (QED) based on nanophotonic devices. A cavity QED system is a hybrid system with photons and atoms confined in an optical cavity, and it is an ideal interface between atomic and photonic qubits. We develop novel nanophotonic devices, such as optical nanofiber cavities, and construct cavity QED systems. Based on such systems, we will aim to realize scalable quantum technologies.
