Postdoc in Measurement-Device Independent Secure Quantum Communication using Entanglement Sources - DTU Physics

We are seeking an outstanding and highly motivated postdoctoral researcher to join our team in pioneering next-generation secure quantum communication systems. The successful candidate will contribute to cutting-edge research on measurement-device-independent (MDI) quantum communication protocols based on entanglement-based sources, with the goal of enabling scalable, high-performance quantum networks.
By joining us, you will contribute to cutting-edge experimental research, work in state-of-the-art quantum optics laboratories, and collaborate closely with leading international partners in quantum communication and photonics. You will be part of the Quantum Physics & Information Technology (QPIT) section at DTU Physics—a dynamic, ambitious, and highly international research environment at the forefront of quantum technologies.
The position offers competitive employment conditions, including university salary, potential tax benefits for international researchers, and support for conference travel and professional development.
If you aim to advance your career in experimental quantum optics and help shape the future of secure quantum communication, we encourage you to apply.
Responsibilities and qualifications
As a postdoctoral researcher, you will work closely with an interdisciplinary team of quantum physicists, photonics engineers, and information theorists.
Your key responsibilities will include:

• Developing broadband entanglement sources.
• Leading the design and realization of phase-locking systems and advanced digital signal processing.
• Designing, building, and optimizing experimental setups for high-rate MDI-CVQKD system.
• Publishing results in high-impact journals and presenting at international conferences.
• Contributing to the supervision of PhD students and the coordination with collaborating researchers.

We are seeking a researcher with strong experience in experimental quantum optics and a clear motivation to advance quantum communication technologies. The successful candidate is expected to demonstrate scientific ambition, creativity in experimental design, and determination to achieve high-impact results.
As a formal qualification, you must hold a PhD degree (or equivalent). 
Moreover, the ideal candidate will have:

• A PhD in physics, optical engineering, quantum technologies, photonics, or a closely related field.
• Proven experience in experimental quantum optics, ideally including squeezed light and entanglement generation.
• Strong hands-on experimental skills and the ability to troubleshoot complex optical and electronic systems.
• Experience with high-speed data acquisition, digital signal processing, and optical phase-locking techniques.
• The ability to work independently while contributing effectively to a collaborative research environment.
• A proactive and open mindset, including a willingness to share expertise and support junior researchers.
• Enthusiasm for contributing to the development of high-rate, scalable quantum communication technologies.
