The current information era closely relates to the Internet technology with traffic projected to grow exponentially in years to come. Although there are many proposals on how to deal with the upcoming bandwidth capacity crunch, the security of optical networks seems to be almost completely neglected. By taping out the portion of a dense wavelength division multiplexing signal, huge amounts of data can be compromised. Therefore, the security of the future network infrastructure is becoming one of the major issues—to be addressed sooner, rather than later. In this project, the University of Arizona (UA) team will coherently utilize the concepts of cryptography, quantum information theory, and nanophotonics to develop the next generation of quantum-enabled secure communication networks. The proposed project will significantly contribute to the major effort of providing ultimate security for future information infrastructure in the US as well as globally. At the same time, the proposed high-speed, secure, reliable quantum networking approaches will be a framework for cross-disciplinary research in quantum networks, cryptography, quantum information theory, quantum nanophotonics, coding theory, and fiber-optics technologies. This project will advance the quantum information science and technology by formulating a new framework to enable high-rate, robust, and scalable terrestrial quantum communication networks (QCNs) that use novel hybrid continuous variable (CV)-discrete vari
