QuEST: Overview

Quantum Experiments using Satellite Technology (QuEST)

The age of quantum technologies is imminent and the enhancement in the computational power can pose a threat to the various cryptographic standards currently being used in secure communication, all over the world. The security of most of the widely used cryptographic algorithms are based on mathematical problems, which cannot be solved in reasonable time using classical computation. Hence, coming up with new techniques to retain the level of security in communication is the need of the hour, QKD being one of them. Lot of research is being undertaken all over the world to come up with various implementations of QKD having better key generation rate and security as well as increasing the distance over which this can be performed, which is relevant to the national security as well. Our work is motivated towards developing such technologies from an indigenous perspective.
