In a groundbreaking achievement, DRDO and IIT-Delhi have demonstrated secure quantum communication using entanglement over a distance, marking a significant stride in India’s quantum tech capabilities. This setup, achieved through entangled photons, promises ultra-secure data links resilient to eavesdropping—critical for defence and high-security communications.
This advance propels India into the global quantum communication arena, often led by the US, China, and Europe. Practical challenges remain, such as long-distance transmission and cost-effective deployment. Nonetheless, this prototype opens doors for quantum networks that could eventually connect strategic sites across the country with near‑unbreakable encryption.
