Abstract: Optical communications have enabled high-speed data transmission over long distances. However, data are transmitted plain unless are encrypted on higher layers, e.g., IP and TCP, precisely because of: i) the high data rates; and ii) the need of secure key exchange between the end-points of the optical connection. Meanwhile, quantum enabled cryptography has emerged as a promising solution for securing communications by leveraging the principles of quantum mechanics which provides unlimited and unconditional security. Although Quantum Key Distribution (QKD) protocols can deliver quantum keys to distant end-points, there are scenarios where one of them is not within the security perimeter of the quantum network. This demonstration focuses on the intersection of optical communication and quantum security, highlighting the synergies between these two domains and their potential to ensure secure communication networks. We explore the integration of optical communication with quantum technologies and showcase how optical encryption using quantum keys retrieved from QKD and Quantum Random Number Generator (QRNG) systems is performed. Retrieved keys are expanded to the required rate and then used to encrypt the input data at line speed.
