Abu Dhabi is building a ground station to catch quantum-secured signals from satellites, part of a push to keep sensitive government and commercial traffic beyond the reach of future code-breaking machines.
The work sits at the Technology Innovation Institute, where Dr Sana Amairi-Pyka leads quantum communications and directs the Abu Dhabi Quantum Optical Ground Station project. Quantum key distribution sends encryption keys encoded in the quantum states of individual photons. Because measuring a photon disturbs it, an eavesdropper leaves a trace, and two parties who see that trace can discard the key.
Why satellites suit the job
Optical links between a spacecraft and a telescope on the ground can cross distances that fibre cannot match, particularly between continents where no dedicated cable runs. A satellite passes overhead on a known track, so pointing is predictable, and free-space transmission avoids the losses that accumulate over long terrestrial fibre routes.
The quantum computer deadline
The urgency comes from the other direction. Today’s public-key cryptography rests on problems that a large enough quantum computer would solve quickly, and traffic intercepted now can be stored and opened later. Material with a long secrecy life, including military and intelligence data, needs protection first.
The institute frames the ground station as a step toward putting the UAE among the countries that operate space-based quantum communications, rather than as a finished service. Dr Amairi-Pyka said the project aims to position the emirate as a pioneer in the field.
