About this position
This PhD project at Eindhoven University of Technology focuses on entanglement routing in quantum optical fiber networks, combining theory, simulation, and experimentation to build telecom-grade quantum networking technologies.
You will develop an entanglement-based routing architecture and protocol and set up an experimental multi-node testbed for routing entangled photons alongside classical telecom traffic. The project investigates how quantum-classical packets can be generated, detected, frequency-converted, and switched between nodes connected by optical switches, while studying the effects of noise, crosstalk, and other coexistence impairments.
The work is hosted in the Smart Optical Networks Lab (SONL) within the Electro-Optical Communication group. SONL’s research spans network design, software control, reconfigurable interconnects for telecom, datacenters, AI clusters, quantum networks, and heterogeneous photonic integrated circuits. The broader ECO group works across the communication system stack, from the photonic layer to the application layer, and is active in TU/e’s Casimir Institute as well as the PhotonDelta and QuantumDelta growth fund programs.
The project is industry-linked through KPN, and aims to address real-world constraints such as scalability, interoperability, reliability, and manageability for quantum networks. In addition to research, the PhD candidate will contribute to teaching in the Department of Electrical Engineering and mentor BSc and MSc students.

What's required
A master’s degree or equivalent university degree in applied physics, electrical engineering, or a related subject is required. Applicants should have a solid background in fiber-optic communication, quantum optics, and networks, and knowledge of programming languages such as Python. Prior experience with quantum optical communication and network experiments is an asset, and a background in Electronics/FPGA is a plus. Candidates should have a research-oriented attitude, be able to work in an interdisciplinary team and collaborate with industrial partners, be motivated to develop teaching skills and coach students, and be fluent in spoken and written English at C1 level.
