Postdoc in High-Speed Secure Quantum Communication with Squeezed Light DTU Physics

We are seeking a highly talented postdoctoral researcher to advance our research on high-speed quantum communication based on squeezed states of light. The position offers the opportunity to take a central role in developing next-generation continuous-variable quantum communication systems including high-bandwidth squeezed-light sources ultralow-noise detection and advanced DSP methods.

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 a dynamic and highly international research environment within the Quantum Physics & Information Technology (QPIT) section at DTU Physics.

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:

• Conducting experimental research in high-speed continuous-variable secure quantum communication using a broadband squeezed-light source and advanced digital signal processing (DSP).
• Leading the development of lightweight DSP pipelines for high-speed real-time implementation.
• Designing and optimizing experimental setups to achieve low-noise high-rate performance.
• 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.

Moreover the ideal candidate will have:

• A PhD in physics optical engineering quantum technologies photonics or a closely related field.
• Documented experience in quantum optics experiments preferably involving squeezed light coherent detection or continuous-variable systems.
• Strong experimental and problem-solving skills including the ability to debug complex optical/electronic systems.
• Experience with high-speed data acquisition signal processing or FPGA/GPU-based DSP is considered an advantage.
• 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.
