Chao Lei

Chao Lei is a Postdoctoral Researcher at the Department of Electrical Engineering, Chalmers University of Technology, Sweden. His work focuses on quantum communication, secure optical networking, and AI integration in photonics, with affiliations to the Optical Networks (ON) unit.

• Ph.D. from Beijing University of Posts and Telecommunications (2023)

Research interests include Quantum-ROADM for quantum internet infrastructure, Physical-layer secure optical communication (e.g., quantum noise stream cipher, secure key distribution), and coherent optical communication systems. Recent publications highlight hybrid quantum-classical network characterization, QKD security in multiplexing systems, and AI-driven optical security protocols.

The three publications (2024–2025) emphasize quantum network vulnerabilities, secure coherent system design, and optical switching impairments. Collaborations with institutions like KTH Royal Institute of Technology and funders such as VINNOVA and Wallenberg Center for Quantum Technology (WACQT) underscore his research impact.
