Hyderabad: QNu Labs reported strong quantum security performance of its ARMOS platform after a global study validated its deployment readiness under real-world conditions.
The study, conducted in collaboration with VIAVI Solutions using the MAP-300 testing platform, assessed the system’s ability to support secure communication across enterprise and critical infrastructure networks. As a result, the findings confirmed reliable performance under varying telecom conditions.
Quantum security performance validated across real-world conditions
The quantum security performance of ARMOS was demonstrated through secure key generation over distances of up to 200 km on standard telecom fibre without signal amplification. Additionally, the system maintained quantum bit error rates below 4%, which fall within acceptable operational thresholds.
At metro distances of around 50 km, the platform generated up to 8,000 secure bits per second. Meanwhile, at extended distances of 200 km, it sustained approximately 200 secure bits per second. Therefore, the results highlight stable performance across different network ranges.
ARMOS integrates with existing telecom infrastructure
The study also showed that ARMOS could operate alongside 10 Gbps classical data traffic on the same fibre. Importantly, it did not degrade the quantum channel, which addresses a major integration challenge.
Moreover, the system detected and recovered from simulated fibre cuts within minutes. It restored secure key generation automatically, without requiring manual intervention. This capability ensures resilience in real-world network conditions.
Advanced protocol enhances system efficiency
QNu Labs attributed the results to its decoy-state Differential Phase Shift protocol. This technology supports operation at up to 40 dB channel loss and extends transmission range compared to conventional systems.
In addition, the platform performed effectively under challenging conditions such as attenuation and polarisation changes. These results reinforce its suitability for large-scale deployment.
Push towards quantum-resilient infrastructure
Officials from both organisations said the findings represent significant progress in deploying scalable quantum-safe systems. They also outlined plans for further testing under higher data loads and expanded network environments.
Overall, the validated quantum security performance supports efforts to build quantum-resilient infrastructure and enables wider adoption of advanced secure communication technologies.
