(TheHindu) India’s Defence Research and Development Organisation (DRDO) on Wednesday successfully demonstrated communication between its two labs using Quantum Key Distribution (QKD) technology, which is a “robust” way to share encryption keys, said an official statement.
Defence Minister Rajnath Singh congratulated the DRDO for successful demonstration of QKD-based communication between its two labs in Hyderabad, said the statement.
The Defence Research and Development Laboratory (DRDL) and The Research Centre Imarat (RCI) were the two labs that participated in this demonstration.
“Quantum Communication using the time-bin QKD scheme was performed under realistic conditions. The setup also demonstrated the validation of detection of a third party trying to gain knowledge of the communication,” the statement added.
Time-bin encoding is used to encode qubit on a photon.
