A milestone of the Quantum Communication project was achieved when DRDO developed Quantum Key Distribution (QKD) technology underwent trials in Hyderabad between two DRDO labs, DRDL and RCI, to show secure communication. With increased hacking and competitiveness the defence and strategic agencies requires secure communications. Quantum based communication offers a robust solution to sharing the keys for encryption securely. Defence Research & Development Organisation (DRDO) undertook the project for development of this technology. 

Defence Minister Rajnath Singh congratulated the DRDO team for successful demonstration of QKD communication. The technology is developed by CAIR, Bengaluru and DYSL-QT, Mumbai. Quantum Communication using time-bin Quantum Key Distribution (QKD) scheme was performed under realistic conditions. It also demonstrated the validation of detection of a third party trying to gain knowledge of the communication. Quantum based security against eavesdropping was validated for the deployed system at over 12kms range and 10dB attenuation over fibre optic channel. 

The work being done at DRDO will be used to enable start-ups and SMEs in the domain of Quantum information technologies. It will also serve to define standards and crypto policies that can leverage QKD system in a unified Cipher Policy Committee (CPC) framework for more secure and pragmatic key management for current and future military cryptographic systems.
