What if a quantum computer could break the encryption we use today to secure our data? QSA Technology, a quantum start-up and spin-out from Pepijn Pinkse’s lab, is working to tackle this challenge. Based in Twente, they address the gap of identity authentication and work on a solution to overcome the threat to our digital security.  

QSA Technology’s photonic integrated circuits deliver digital fingerprinting capabilities that could transform telecommunications, satellite communications, cloud providers, and hyperscalers. The patent-protected chips function as a unique key, determined by random microscopic imperfections created during manufacturing. When a light pulse passes through the chip, the output is a unique, quantum-secure pattern, serving as a ‘fingerprint’ for authentication. 

As current methods fall short, there's an urgent need for innovative approaches to secure our data for the future. Post-quantum cryptography, used by companies like Google and Microsoft, lacks the hardware-level security and physical guarantees offered by quantum-secure technologies. Similarly, traditional authentication in Quantum Key Distribution systems offers encryption relying on classical cryptographic methods which are not quantum-secure and are vulnerable to quantum computing attacks.

QSA Technology fills these gaps by delivering a hardware-based, quantum-resistant solution that complements Quantum Key Distribution and Wireless Optical Communication.
