AHMEDABAD, India (ISRO PR) — On 27 January 2022, scientists from the two premier laboratories of Department of Space (DOS), viz. Space Applications Centre (SAC) and Physical Research Laboratory (PRL), both from the city of Ahmedabad, have jointly demonstrated quantum entanglement based real time Quantum Key Distribution (QKD) over 300m atmospheric channel along with quantum-secure text, image transmission and quantum-assisted two-way video calling.


ISRO to Support Eight Joint Research Projects Proposed by Space Technology Cell at IIT Delhi

NEW DELHI, India (IIT Delhi PR) — The Indian Space Research Organisation (ISRO), Government of India, will support eight joint research projects mooted by the Space Technology Cell (STC), IIT Delhi.  ISRO will support the projects under its RESPOND program with varying duration of 1-3 years.

The Space Technology Cell was set up at IIT Delhi under an MoU signed between ISRO and IIT Delhi in November 2019 with an aim to strengthen the research collaboration between the two organisations and to carry out focused research projects in the space technology domain with specific deliverables.

The eight collaborative research projects on which the scientists from different ISRO centres and IIT Delhi will work jointly include:


ISRO Makes Breakthrough Demonstration of Free-space Quantum Key Distribution (QKD) Over 300 Meters

BENGALURU, India (ISRO PR) — For the first time in the country, Indian Space Research Organisation (ISRO) has successfully demonstrated free-space Quantum Communication over a distance of 300 m.

A number of key technologies were developed indigenously to accomplish this major feat, which included the use of indigenously developed NAVIC receiver for time synchronization between the transmitter and receiver modules, and gimbal mechanism systems instead of bulky large-aperture telescopes for optical alignment.
