Sterlite Technologies Ltd has signed an MoU with QNu Labs to co-develop quantum communication systems using Multi-Core Fibre. The collaboration supports India’s National Quantum Mission and aims to integrate secure Quantum Key Distribution with high-speed data transmission. Successful trials mark a major milestone in building quantum-secure optical networks.

Sterlite Technologies Ltd (STL), a global leader in optical and digital solutions, has signed a strategic Memorandum of Understanding (MoU) with QNu Labs Pvt. Ltd. to advance research and development in quantum communications over optical fibre networks. The partnership marks a pivotal step in building India’s quantum-secure infrastructure under the National Quantum Mission.

Collaboration Highlights

- STL and QNu Labs will co-develop quantum communication technologies, focusing on Quantum Key Distribution (QKD) over Multi-Core Fibre (MCF) networks

- QNu Labs, incubated at IIT Madras and supported by the Department of Science and Technology, is India’s first end-to-end quantum cybersecurity firm

- The MoU aims to integrate STL’s advanced MCF technology with QNu’s QKD systems to enable secure key exchange alongside high-capacity classical data transmission

- Successful demonstrations include secure quantum key exchange over 170 km with 800 Gbps classical traffic, and 150 km with 1.8 Tbps throughput

- STL’s MCF solutions use Space Division Multiplexing across 4-core and 7-core fibres, offering ultra-high transmission capacity without increasing fibre diameter

- These innovations are tailored for hyperscale data centres, 5G networks, Gen AI workloads, and ultra-HD streaming applications

Strategic Implications

- The partnership aligns with India’s ₹6,000 crore National Quantum Mission, which aims to build real-world quantum-secure systems by 2031

- STL’s deployment of MCF at IIT Madras under the DoT-sponsored Advanced Optical Communications Test Bed meets Telecom Engineering Centre standards

- QNu Labs brings expertise in quantum cryptography, secure digital infrastructure, and global deployment experience

- The collaboration will accelerate India’s leadership in quantum-secure communications and support export-ready solutions for global markets

Market Outlook

- India’s quantum communication market is projected to reach USD 139.8 million by 2030, growing at a CAGR of 34.6%

- STL’s continued investment in fibre innovation positions it as a key player in next-gen telecom and cybersecurity infrastructure

- The partnership may influence future government and enterprise procurement strategies for secure data transmission
