PhD Opportunities in Quantum Communication in Japan

This PhD project will develop high-bandwidth quantum frequency converters for future hybrid quantum networks. The research addresses a central challenge in quantum networking: quantum technologies often operate at incompatible optical wavelengths. Visible single-photon sources, telecom communication channels and atomic quantum memories therefore require interfaces capable of translating photons between wavelength regimes. The project will use four-wave mixing in warm rubidium vapour to develop t...

This PhD project at the University of Southampton explores reconfigurable photonic circuits for quantum computing, quantum information processing and secure communication networks. The research focuses on controlling how individual photons travel and interfere within compact, integrated quantum photonic chips. The project will investigate dynamically reconfigurable devices whose optical properties can be programmed for quantum operations. A central approach is the use of electrostatically actuat...
