Deep-tech company transforms operational QKD deployment into a production-scale quantum-safe infrastructure, achieving more than 70 billion times greater effective data transport capacity while preserving quantum-level security.
Lisbon, June 5, 2026
Asociația OncoHelp, one of Romania’s leading oncology organisations, and the Politehnica University of Timișoara (UPT), a major research and technology institution, have successfully deployed a next-generation quantum-safe connectivity infrastructure engineered by QuantumNova. The new architecture enables the secure exchange of critical medical and research data between clinical and academic environments while overcoming one of the biggest limitations ever faced by Quantum Key Distribution (QKD) networks.
Before the deployment, OncoHelp and UPT already operated a dedicated QKD link, an advanced quantum communications infrastructure designed to distribute cryptographic keys using the laws of quantum physics. Such deployments remain rare worldwide and are considered among the most sophisticated approaches to secure communications currently available. However, while QKD provides exceptional security, it was never designed to transport large volumes of data.
The existing infrastructure operated at approximately 5 Kbit per hour. At that speed, transferring a single 1 GB medical file would theoretically require almost 196 years to complete. For organisations exchanging clinical records, diagnostic imaging, oncology research datasets and other critical healthcare information, the limitation represented a significant operational challenge.
QuantumNova solved this challenge by redesigning the underlying communications architecture.
Instead of transporting both keys and data through the quantum channel, the company introduced a dual-plane quantum-safe architecture. Cryptographic keys continue to be generated and exchanged through the existing QKD infrastructure, preserving the quantum security model already deployed by OncoHelp and UPT. The data itself is encrypted using those quantum distributed keys and transmitted through a dedicated 100 Gbps fibre network protected by advanced Post-Quantum Cryptography.
This approach combines two of the most important cybersecurity technologies of the coming decades: Quantum Key Distribution for trust establishment and key exchange, and Post-Quantum Cryptography for ultra high-speed data transport.
The result was transformative! The same 1 GB file that would previously have required approximately 196 years to transfer can now be delivered in approximately 0.086 seconds, almost as fast as the blink of an eye. Effective transport capacity increased from 5 Kbit/hour to 100 Gbps, representing an improvement of more than 70 billion times while maintaining quantum-secure key distribution.
The infrastructure is powered by QuantumNova’s QS-WAN platform, which provides a Quantum-Safe Overlay Network, Distributed Secure Control Plane, Cryptographically Governed Data Exchange and Identity Centric Network Architecture. Through the platform, authorised researchers, clinicians and medical personnel can securely access systems and data across multiple sites. Doctors working from hospitals and clinics can also establish secure remote access to OncoHelp resources using the QNova Client, a quantum-safe access solution that integrates directly with the wider infrastructure.
The deployment also incorporates a Hybrid PQC Key Exchange framework, ML-DSA certificate infrastructure, Cryptographic Agility Framework and Harvest Now, Decrypt Later mitigation strategies, allowing the architecture to evolve alongside future quantum-resistant standards without requiring fundamental redesign.
For the quantum networking community, the significance extends well beyond healthcare. The project demonstrates how existing QKD deployments can evolve from highly secure but bandwidth-constrained environments into production-grade infrastructures capable of supporting real world workloads at scale. It provides a blueprint for hospitals, research institutions, governments and critical infrastructure operators seeking to preserve their investment in quantum communications while achieving the performance levels required by modern digital systems.
