A joint team of scientists from the Defence Research and Development Organisation (DRDO) and Indian Institute of Technology (IIT) Delhi successfully demonstrated Quantum Key Distribution (QKD) link between Prayagraj and Vindhyachal in Uttar Pradesh, a distance of more than 100 kilometres. The technological breakthrough was achieved over the commercial-grade optical fibre already available in the field.
This technological breakthrough was achieved over a commercial-grade optical fibre already available in the field.
With this success, the country has demonstrated indigenous technology of secure key transfer for bootstrapping military-grade communication security key hierarchy.
In December 2020, the technology was tested for communication between two DRDO facilities in Hyderabad—the Defence Research and Development Laboratory (DRDL) and Research Centre Imarat (RCI)—over a distance of 12 km.
Why do we need QKD
QKD is essential to address the threat that rapid advancement in Quantum Computing poses to the security of the data being transported by various critical sectors through the current communication networks.
The technology would be useful in enabling various start-ups and small and medium enterprises in the domain of quantum information.
It is expected to create a definition of standards and formulate crypto technology-related policies.
