As social media and online modes of communications are taking increasingly integral roles in our lives, the threat to privacy is increasing. Encryption becomes crucial for bank transactions, satellite communication, defense, and all modes of communication. Social media apps such as WhatsApp, Telegram and Facebook Messenger promise end-to-end encryption and a safe platform for conversations. However, scientists say that the methods of encryption are not as robust as they should be.
Keeping this in mind, an Indian scientist recently made a scientific breakthrough in making communication secure, in the domain of free-space quantum communications. Professor Urbasi Sinha, who heads the Quantum Information and Computing Lab, part of the Light and Matter Physics group at the Raman Research Institute (RRI) Bengaluru, has succeeded in securing quantum communication between two parties using an atmospheric free space channel.
“The conventional method in securing communication is to use…
