- The Indian Space Research Organisation (ISRO) successfully demonstrated free-space Quantum Communication over a distance of 300 metres.
- This is a first-of-its-kind initiative.
- The demonstration has included live videoconferencing using quantum-key-encrypted signals.
- This is a major milestone achievement for unconditionally secured satellite data communication using quantum technologies.
- This is demonstrated at Space Applications Centre (SAC), Ahmedabad, between two line-of-sight buildings within the campus.
- The experiment was performed at night, in order to ensure that there is no interference of the direct sunlight.
- The experiment is a major breakthrough towards ISRO’s goal of demonstrating Satellite Based Quantum Communication.
