Spooky but secure: A big leap for ISRO in quantum communications

Using quantum computers for calculations involves using the superpower of superposition

Scientists from Ahmedabad’s Space Applications Centre and Physical Research Laboratory have used quantum entanglement to create a hack-proof communications system. This is a terrific achievement putting India in the first rank when it comes to developing knowhow about quantum-encryption.

The press release says real-time quantum key distribution (QKD) was used to conduct hack-proof communications between two places separated by 300 metres. Scientists created a channel to share secure text, image transmissions and two-way video calling. The experiment was conducted between two buildings at the Space Applications Centre.

The experiment was repeated multiple times to ensure the repeatability and robustness of
