Quantum technologies enable solutions providing e.g. unconditionally secure information transfer or ultrasensitive detectors. They use entanglement, superposition and interactions at a single quanta level. Time-frequency integrated quantum optics is ideally suited for these tasks: flexible, scalable, robust to losses, offers high control of single photons. Its potential has not yet been explored. In this project, we plan to build high-quality random number generator and nanodevices based on graphene plasmons. To this end, we will advance the platform, producing pure spectrally-shaped single photons at 1550nm which interfere. Its features will allow to surpass the present technology to produce true randomness and study photon-plasmon interactions in the smallest graphene samples in the world. The young team will learn from top specialists in integrated optics: the University of Paderborn and the University of Oxford and will serve as a hotbed of professional R&D staff for the industry.
