Day-to-Day Responsibilities
Design quantum communication links, such as fibre routes that carry quantum key distribution (QKD) signals alongside normal internet traffic.
Set up and calibrate the optical components, single-photon detectors and trusted nodes that keep quantum signals stable over distance.
Plan how quantum-secured links connect with existing classical networks, routers and data centres.
Test link performance, measure signal loss and error rates, and troubleshoot faults in the lab or in the field.
Work with physicists and software teams to integrate key management and encryption into live systems.
Document designs, monitor links, and report on security and reliability to project managers and clients.
Track developments in post-quantum cryptography so that networks can move to quantum-resistant encryption on time.
