Hyderabad: QNu Labs reported strong quantum security performance of its ARMOS platform after an independent global study validated its deployment readiness under real-world conditions.
The study, conducted with VIAVI Solutions using the MAP-300 testing platform, assessed the system’s ability to support secure communication. It focused on enterprise and critical infrastructure networks. Moreover, it confirmed that ARMOS operated reliably across varying telecom conditions.
QNu Labs said the platform achieved secure key generation over distances of up to 200 km on standard telecom fibre. It did so without signal amplification. Additionally, it maintained quantum bit error rates below 4%, which fall within acceptable thresholds.
QNu Labs demonstrates quantum security performance with ARMOS
At metro distances of about 50 km, the system generated up to 8,000 secure bits per second. However, at extended distances of 200 km, it sustained around 200 secure bits per second. Therefore, this reflected stable quantum security performance across ranges.
The study also found that ARMOS functioned alongside 10 Gbps classical data traffic on the same fibre. Importantly, it did not degrade the quantum channel. As a result, this addressed integration challenges and avoided network redesign.
QNu Labs said the system detected and recovered from simulated fibre cuts within minutes. It restored secure key generation without manual intervention. Further, it performed under real-world conditions such as attenuation and polarisation changes.
The company attributed this performance to its decoy-state Differential Phase Shift protocol. This supports operation at up to 40 dB channel loss. Consequently, it extends transmission range compared to conventional systems.
Officials from both organisations said the findings marked progress in deploying scalable quantum-safe systems. They also outlined further testing under higher data loads. Meanwhile, they plan extended network evaluations.
QNu Labs said the results support efforts to build quantum-resilient infrastructure. In addition, they enable wider adoption of secure communication technologies.
