High-speed quantum-secure optical networks
Annotation in Czech
Secure quantum communication, being the most advanced of the emerging quantum technologies, offers provably information-theoretically secure information exchange between trusted parties. While the technology continues to develop, its functionality is still limited by relatively low communication rates and by mostly point-to-point communication topologies. Use of continuous-variable quadratures of light naturally allows to split the quantum signal between several network users, while also benefiting from compatibility with telecom technologies and fast and efficient coherent detection. Extending the ongoing cooperation between Palacky University in Olomouc and Technical University of Denmark we will advance existing continuous variable quantum key distributing networks by increasing their capacity and scalability. Using channel multiplexing, we will develop and test scalable high-speed continuous-variable optical networks, that can deliver quantum-secure communication simultaneously to multiple end-users.
