Join us for an exciting and excellent Doctoral student journey to create the future of networks!
The division of Communications, Antennas and Optical Networks conducts cutting edge research covering several aspects of communication infrastructures. The Optical Networks (ON) group performs research in network architecture design and optimization, control and management, datacenter networks, fiber access and mobile transport networks, network sustainability, reliability, security and survivability, converged fiber-wireless networks, and optical quantum networks.
The quantum network is anticipated to surpass the classical network in both computing power and security. As a fundamental component of the classical network, the adaptable optical communication network must take on the task of facilitating the transition to these new communication and computing paradigms by linking quantum processors in a networked manner.
This project focuses on designing and developing optical switching testbeds and networking protocols for Quantum networks. The goal is to enable secure, low-latency, and scalable communication between distributed quantum information processing platforms. The research integrates quantum communication principles with high-speed optical networks, emphasizing entanglement-aware routing, quantum compatibility, and system-level performance evaluation. The candidate will develop a hybrid simulation framework and prototype optical switching solutions to support future quantum networking and distributed quantum computing architectures.
