The scientists from the Ahmedabad-based Space Applications Centre and Physical Research Laboratory successfully demonstrated quantum entanglement.
Using real-time Quantum Key Distribution, they conducted hack-proof communication between two places separated by 300 meters.
Quantum communication is one of the safest ways of connecting two places with high levels of code and quantum cryptography that cannot be decrypted or broken by an external entity.
If a hacker tries to crack the message in quantum communication, it changes its form in such a manner that would alert the sender and would cause the message to be altered or deleted.
