Quantum Communications Engineer – The Schools' Aerospace Careers Programme

What Does This Career Involve?

Quantum Communications Engineers develop systems that harness the principles of quantum mechanics — such as entanglement and photon polarisation — to transmit data securely. Their work includes building quantum key distribution (QKD) systems, integrating them into satellites, and enabling Earth-to-space encryption networks. They collaborate across physics, engineering, and computing to make quantum-secure communication a reality.

Why Is This the Future?

As cyber threats grow, quantum encryption offers unbreakable security for defence, finance, and data infrastructure. Satellites equipped with quantum communication technology are already being tested. Engineers in this field are pioneering the backbone of a future internet that’s not only faster — but fundamentally more secure.
