Colt Technology Services (Colt), a leading global provider of digital infrastructure, announced a strategic collaboration with Honeywell and Nokia to explore quantum-safe networking using satellite-based communications. This joint initiative aims to test innovative methods for safeguarding encrypted optical network traffic against the evolving threats posed by quantum computing.
As the power of quantum computing grows, it introduces new cybersecurity risks. Unlike traditional encryption—which relies on complex mathematical algorithms difficult for current computers to break—quantum computers could potentially solve these problems at unprecedented speeds, rendering conventional cryptographic methods vulnerable. To stay ahead of these threats, the collaboration will focus on next-generation encryption technologies that are designed to be resistant to quantum attacks.
At the core of this exploration is Quantum Key Distribution (QKD), a cutting-edge approach that securely shares encryption keys between parties. While QKD is a key enabler of secure communication in the quantum era, it faces a significant challenge: current terrestrial implementations are limited to approximately 100 kilometers due to physical constraints. By leveraging satellite communications, this limitation can be overcome—enabling secure, long-distance transmission, even across transatlantic links.
Colt, Honeywell, and Nokia will jointly test QKD using low earth orbit (LEO) satellites, enabling ultra-long-distance and cross-ocean data protection. This collaboration is particularly relevant for industries that manage large volumes of sensitive data, including finance, healthcare, pharmaceuticals, and government sectors.

At Colt, we do everything we can to make life easier for our customers. It’s why we’re taking action now to protect our customers from future cybersecurity risks, tackling tomorrow’s threats, today,” said Buddy Bayer, chief operating officer, Colt Technology Services.
“With over five decades of aerospace expertise, Honeywell has witnessed and adapted to the evolution of the global communications landscape. We are proud to continue as a leader in innovating future-proof solutions such as the QEYSSat and QKDSat missions for the quantum era. This collaboration represents a significant step forward in securing the future of critical data: designing solutions to enhance resilience, ensuring long-term data security for critical infrastructure and communications systems,” said Lisa Napolitano, vice president and general manager, Space, Honeywell Aerospace Technologies.
“Nokia is helping our customers stay ahead when it comes to securing critical data through resilient defense-in-depth strategies. Quantum computing brings great promise, but it’s also a potential threat to the encryption models on which society has relied so far. This collaboration with Colt and Honeywell shows how space-based quantum-safe technologies can help protect networks, safeguarding sensitive information across every domain against future quantum threats,” said James Watt, vice president and general manager, Optical Networks at Nokia.
This multi-industry partnership reflects a shared commitment to proactive innovation, ensuring that businesses and governments can harness the potential of quantum computing—while securing their most vital digital assets.
