India, April 21 -- In a notable advancement towards the development of quantum-secured communication networks in India, the Centre for Development of Telematics (C-DOT) and Sterlite Technologies Limited (STL) have successfully completed the country's first Quantum Key Distribution (QKD) transmission using a four-core Multi-Core Fibre (MCF).

By enabling data transfer across multiple cores within a single fibre, Multi-Core Fibre (MCF) technology presents an effective solution that significantly reduces infrastructure costs and physical space requirements. According to the Ministry of Communications, MCF allows for the physical separation of quantum and classical signals into distinct cores within a single fibre. In the context of Quantum K...
