Q-net-Q

ongoing

The increasing demand of digital communication networks with higher bandwidth and denser networks requires new efficient and secure communication channels, due to the fact that today's infrastructure is leveraged as a new attack vector by foreign countries. In today's Internet Service Provider (ISP) network infrastructure, the technical lack of security technologies makes it difficult to achieve the goal of guaranteed, accepted and integrated security in data transmission, cryptographic key distribution, and random number generation. In an increasingly networked information society, the security of digital system components is an essential building block for their success. Entangled quantum communication is a promising technology for physically guaranteed security, randomization, and data transmission. Therefore, the players in information and communication technologies (ICT), as operators of today's Internet network infrastructures, are required to make increased efforts with quantum physicists to be able to effectively guarantee secure communication in today's data networks. Digital progress, for example through Quantum Key Distribution (QKD), based on either single-qubit or entangled resources, enables the shift from cryptographic key transmission through mathematical methods of factoring large numbers to guaranteed security through fundamental physical processes of quantum mechanics. However, such quantum communication applications are currently not used enough in existing telecommunications networks, since the system integration and long-term stability of these components in ICT networks requires a cost-efficient technology transfer. The Q-net-Q project leverages such technology to build a reliable and secure communication channel between networked entities such as government, critical infrastructure (KRITIS), and military as well as publicly used infrastructure such as eHealth, data centres, and traditional communication networks.
