▶️ QNu Labs, in collaboration with Bhaskaracharya National Institute for Space Applications and Geo‑informatics (BISAG‑N) and IIT Gandhinagar, has successfully demonstrated India’s first free‑space Quantum Key Distribution (QKD) link at a scale of 5.56 km
▶️ The field trial, conducted on the night of September 27–28, established a secure quantum communication channel between BISAG‑N and IIT Gandhinagar
▶️ Using QNu Labs’ Pointing, Acquisition and Tracking system, the trial achieved a stable Quantum Bit Error Rate below 5% and generated secure keys at a rate of 230–260 bps
▶️ The trial provides a foundation for advancing India’s capabilities in secure communication infrastructure, strengthening resilience against emerging quantum‑era security threats
