- Colt Technology Services completes a quantum-secured encryption trial across its optical network.
- The trial involved multiple technology partners, aiming to protect businesses from quantum computing risks.
What happened: Groundbreaking trial completed
Colt Technology Services has successfully concluded a quantum-secured encryption trial across its optical wave network. The trial included technology partners Adtran, Ciena, ID Quantique (IDQ), Nokia, and Toshiba. They explored new methods for global businesses to mitigate risks posed by quantum computers to classical encryption keys. This is a significant step towards offering quantum-secured services that can be tailored to meet individual customer requirements. It enhances Colt’s existing Optical Encryption portfolio.
The trial evaluated various quantum-secured encryption methods. These included Quantum Key Distribution (QKD), Pre-Shared Key (PSK) with symmetric key distribution, and Post Quantum Cryptography (PQC) technology. Tests were conducted over Colt’s long-distance network between London and Frankfurt, spanning 1,361 km. They were also carried out in its metro network across London and Slough, covering 88 km. The results demonstrated the feasibility of integrating these advanced encryption techniques into existing infrastructure. This provides enhanced security against future quantum threats.

Why it is important
The successful completion of Colt’s quantum encryption trial highlights the growing importance of preparing for the quantum era. As quantum computing advances, traditional encryption methods face potential vulnerabilities. These include ‘harvest now, decrypt later’ attacks and the anticipated Q-Day, when quantum computers could break classical encryption. Colt’s trial addresses these concerns by demonstrating practical solutions that can be deployed today to safeguard data for the future.
The financial services industry, expected to be among the first to adopt quantum technologies, stands to benefit significantly from these developments. Deloitte Insights forecasts that the financial sector’s investment in quantum computing will grow at a 10-year CAGR of 72%, reaching US$19 billion by 2032. Use cases include risk management, fraud detection, portfolio optimisation, and securing financial operations. Colt’s quantum-secured solutions are poised to provide the necessary security for these applications. This ensures that businesses can confidently navigate the quantum transition.
