Day-to-Day Responsibilities
Design QKD links that send single photons over optical fibre or free space to generate shared secret keys.
Set up and align optical components such as photon sources, beam splitters and single-photon detectors.
Measure quantum bit error rates and noise to check whether a link is secure and reliable.
Integrate QKD equipment with existing classical encryption and network infrastructure.
Test and troubleshoot hardware and control software in lab and field conditions.
Work with cryptography and security teams to assess how keys are used in real applications.
Document designs, test results and security assumptions for review and certification.
