Introduction
IIT Delhi and the Defence Research and Development Organisation (DRDO) have recently demonstrated advanced quantum communication technologies in New Delhi. This collaboration aims to enhance secure communication for critical sectors such as defence and finance.
Overview of Quantum Communication Technologies
The demonstration included Quantum Key Distribution (QKD) over a 50 km fibre link in the laboratory and an 8 km optical fibre across the IIT Delhi campus. Additionally, free-space entanglement distribution was showcased using the BBM-92 protocol over short distances.
Key Achievements
- Fibre-Optic QKD: Successfully demonstrated QKD over 50 km in the lab and 8 km on campus.
- Free-Space Entanglement: Demonstrated entanglement distribution over 20 meters in the lab and 80 meters in open space.
-
Hybrid Entanglement: Achieved a low Quantum Bit Error Rate (QBER) of around 6% over 10 meters in the lab.
Significance of the Demonstration
These advancements mark a significant step towards robust and tamper-proof communication systems, essential for strategic sectors. The collaboration between IIT Delhi and DRDO is fostering cutting-edge innovations in defence technology.
Future Prospects
The ongoing research and development efforts aim to further enhance quantum communication technologies, making them more reliable and scalable for practical applications.
Conclusion
The demonstration by IIT Delhi and DRDO sets a new benchmark for secure communication technologies, promising a future where sensitive information can be transmitted without fear of interception.
