India Successfully Tests First Quantum Key Distribution Over Multi-Core Fibre
| Aspect | Details |
|---|---|
| Event | India's first Quantum Key Distribution (QKD) transmission over 4-core Multi-Core Fibre (MCF) |
| Key Organizations | C-DOT (Centre for Development of Telematics) and Sterlite Technologies Ltd. (STL) |
| Distance Achieved | Exceeding 100 km |
| Core Utilization | 1 core for QKD (quantum signal), 3 cores for high-speed classical data traffic |
| Significance of MCF | Physical separation of quantum and classical signals, simultaneous transmission, cost reduction |
| Technology Approval | C-DOT's QKD systems approved by Telecommunication Engineering Centre (TEC) |
| Security and Efficiency | Quantum-secured communication co-exists with conventional data traffic on a single optical fibre |
| Collaboration | Public-private partnership between C-DOT (DoT) and STL |
| C-DOT | Premier R&D center under Department of Telecommunications (DoT), focuses on indigenous telecom technology |
| STL | Global leader in optical fibre, connectivity, and digital networks, uses Space Division Multiplexing |
