QKD Security Evaluation Specialist (CV-QKD) at DTU Physics, Denmark
Job Description
DTU Physics is looking for a specialist in the security evaluation of continuous-variable quantum key distribution (CV-QKD) systems. The job is to complete and consolidate ongoing European and Danish work on systematic QKD testing, validation, standardisation and certification: finishing experimental test stations, measuring CV-QKD devices, analysing implementation vulnerabilities and writing the evaluation reports that certification needs. It is a one-year technical position for someone who already has hands-on CV-QKD security-evaluation experience.
