Research Scientist - QKD Implementation Security

You will play a key role in the experimental characterisation of QKD systems, contributing highquality data and physical insight., * Design and carry out experimental tests of QKD transmitters, receivers, and subsystem components.

• Characterise photonic and electronic elements such as sources, detectors and modulators.

Implementation Security

• Generate experimental evidence that supports security analysis, modelling, and mitigation strategies.
• Provide clear, datadriven input to decisions on system architecture and performance tradeoffs.

Collaboration & Contribution

• Work closely with experimental and theoretical teams to ensure security assumptions reflect practical implementation details.
• Contribute to joint research activities with academic and industrial partners.
• Write internal reports, coauthor scientific publications, and present work at conferences.
• Contribute to efforts to develop global standards for quantum technologies.

Do you have experience in Python?, Do you have a Doctoral degree?, * PhD (or equivalent experience) in Experimental Physics, Photonics, Electronic Engineering, or a related field.

• Strong handson experience with experimental photonic systems.
• Proven ability to design, execute, and interpret complex measurements.
• Excellent written and verbal communication skills.
• Ability to operate effectively in a collaborative, multidisciplinary research environment., * Knowledge of QKD, quantum optics, or quantum communications.
• Familiarity with implementation security or assurancedriven testing.
• Experimental automation, data analysis, or systemlevel testing experience.
• Experience with QKD systems or closely related platforms.
• Experience with electronics design (PCB development, FPGA programming, highspeed electronics).
