ISRO sets up academic centre for space in KarnatakaChennai, March 23 (IANS) Indian space agency has successfully demonstrated free-space Quantum Communication over a distance of 300 metre with several technologies developed within the country.

“For the first time in the country, Indian Space Research Organisation (ISRO) has successfully demonstrated free-space Quantum Communication over a distance of 300 metre,” ISRO said.

According to ISRO, 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.

The demonstration has included live video conferencing using quantum-key-encrypted signals.

This is a major milestone achievement for unconditionally secured satellite data communication using quantum technologies, ISRO said on Monday.

The Quantum Key Distribution (QKD) technology underpins Quantum Communication technology that ensures unconditional data security by virtue of the principles of quantum mechanics, which is not possible with the conventional encryption systems.

The conventional cryptosystems used for data-encryption rely on the complexity of mathematical algorithms, whereas the security offered by quantum communication is based on the laws of Physics.

Therefore, quantum cryptography is considered as ‘future-proof’, since no future advancements in the computational power can break quantum-cryptosystem, ISRO said.

The free-space QKD was 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.
