5. India Advances in Quantum Communication Technology
Why in News?
India has demonstrated its first 5.56-km free-space Quantum Key Distribution (QKD) link, representing an important step towards developing secure quantum communication systems. The demonstration involved QNu Labs, BISAG-N and IIT Gandhinagar.
Key Points
• Quantum Key Distribution uses principles of quantum mechanics to enable the secure exchange of cryptographic keys.
• An attempt to intercept the quantum channel can alter the quantum state, allowing potential detection of eavesdropping.
• Free-space QKD can be particularly useful in locations where establishing conventional fibre-optic links is difficult.
• The technology could have applications in defence, financial systems, telecommunications and other sensitive communication networks.
• Building domestic expertise in quantum communication can strengthen India's cybersecurity and strategic technology capabilities.
