ISRO makes breakthrough demonstration of free-space

For the 1st time in India, Indian Space Research Organisation (ISRO) successfully demonstrated free-space Quantum Communication over a distance of 300 Metres. The free-space QKD (Quantum Key Distribution) was demonstrated at Space Applications Centre (SAC), Ahmedabad, Gujarat.

  • It is a major milestone achievement for unconditionally secured satellite data communication using quantum technologies.
  • Technology – QKD is the technology behind Quantum Communication Technology.
  • A number of indigenously developed technologies such as NAVIC (Navigation with Indian Constellation) receivers were used for the demonstration.

Benefits

  • Quantum Cryptography is based on the laws of Quantum Physics will be easier than conventional cryptosystems used for data-encryption rely on the complexity of mathematical algorithms.
  • It is considered ‘Future-proof’ since no future advancements in computational power can break quantum-cryptosystems.

Future Goal

  • The demonstration is a major breakthrough towards ISRO’s goal of demonstrating Satellite-Based Quantum Communication (SBQC).
  • In the next step, ISRO plans to demonstrate the technology between 2 Indian ground stations.
