QNu Labs' ARMOS QKD Delivers Carrier-Grade Performance in Independent Global Study with VIAVI Solutions

Source: QNu Labs Validates Real-World Performance of ARMOS QKD in Independent Global Study with VIAVI

QNu Labs has published findings from an independent research study conducted with VIAVI Solutions, a global leader in network test and measurement. The study validated the real-world performance and deployment readiness of QNu's patented ARMOS quantum key distribution platform using VIAVI's industry-recognised MAP-300 test environment.

The results are definitive. ARMOS achieved secure key distribution over 200 km of standard telecom fibre at up to 40 dB of channel loss, without signal amplification, while maintaining low quantum bit error rates throughout. The system operated alongside high-speed classical data traffic with zero degradation and recovered automatically from network disruptions.  

ARMOS is already actively deployed and holds patents and certifications from multiple national and global platforms. As the global leader in testing and validating instruments, VIAVI’s partnership with QNu ensures this independent study validates QKD's capabilities on a global stage.

This performance is driven by QNu Labs’ proprietary decoy-state Differential Phase Shift (DPS) protocol. This innovation allows the system to maintain high-fidelity transmission across a high-attenuation budget, which roughly doubles the effective range compared to standard Quantum Key Distribution (QKD) systems, all while upholding the highest levels of cryptographic security.

The study establishes ARMOS as a field-ready, carrier-grade solution capable of enabling quantum-safe communication across enterprise, telecom, defence, and critical infrastructure networks. For procurement teams evaluating quantum-safe migration, these are not theoretical projections. They are independently measured, third-party validated performance benchmarks on production-grade hardware.

The report also outlines next-phase research, including testing under higher classical data loads, extended link performance beyond current benchmarks, and deeper modelling of hybrid quantum-classical networks.

Developed entirely in India, ARMOS reflects QNu Labs' position as the world's only full-stack hybrid quantum cybersecurity company. The VIAVI validation adds a layer of global credibility that moves the conversation from capability claims to verifiable, repeatable evidence.
