Context: India successfully demonstrated quantum entanglement-based secure communication over 1 km in open air. This breakthrough was achieved by DRDO and IIT Delhi, marking a leap toward unhackable networks.
About India’s Quantum Leap in Communication:
• What Is the Achievement? India has entered the quantum communication era by showcasing Quantum Key Distribution (QKD) in open air using entangled photons, enabling unbreakable encryption.
• India has entered the quantum communication era by showcasing Quantum Key Distribution (QKD) in open air using entangled photons, enabling unbreakable encryption.
• Developed By: Defence Research and Development Organisation (DRDO) Indian Institute of Technology (IIT) Delhi

• How Quantum Communication Works? Utilizes quantum entanglement, where two particles remain interconnected—any change in one instantly reflects in the other. Quantum Key Distribution (QKD) ensures secure sharing of encryption keys. If an eavesdropper tries to intercept, the quantum state collapses, instantly alerting both sender and receiver.

• Key Features of the Breakthrough: One-kilometre Secure Wireless Communication: India achieved quantum communication over a 1-km distance in open air, without relying on fiber cables or lab-enclosed systems. Secure Key Rate – 240 bps: The system successfully transmitted encryption keys at a secure rate of 240 bits per second, suitable for critical data security. Low Error Rate – Below 7%: The quantum link maintained a transmission error rate under 7%, ensuring stability and reliability for practical deployments. Open-Air (Free-Space) Demonstration: Unlike fiber-based QKD, this milestone occurred outdoors, showcasing the feasibility of wireless quantum communication in real-world conditions. Indigenous Quantum Hardware: The entire setup was developed using locally sourced photonic components, marking a step toward Atmanirbhar Bharat in quantum tech.
