After some delay, India is joining a handful of nations that have already embarked on a new kind of space race to build satellite networks for secure “quantum communications”. Existing communications systems are not hack-proof.
Raman Research Institute (RRI) in Bengaluru has joined hands with the Indian Space Research Organisation (ISRO) to develop the quantum technologies that ISRO’s satellites would need to establish such a network.
Quantum communication exploits a bizarre phenomenon of quantum mechanics — called “quantum entanglement” — in which photons (which are particles of light) are “linked” together in such a way that they affect one another no matter how far apart they are. They appear to be connected to each other, as if by magic, and behave as a single physical object.
Because a third party cannot tamper with the photons without destroying their “entanglement”, there’s no way to eavesdrop undetected.
Under the memorandum of understanding signed recently between RRI and ISRO Space Applications Centre (ISAC) also in Bengaluru, the latter will fund the Quantum Information and Computing (QuiC) laboratory at RRI for developing the quantum technology tools.
