India Moves Toward Ultra-Secure Telecom: C-DOT & Synergy To Develop Drone-based Secure Communication

Big move for India's quantum-secure communication! The Centre for Development of Telematics (C-DOT), the premier telecom R&D institution under the Department of Telecommunications (DoT), Government of India, has recently announced partnership with Synergy Quantum India to develop drone-based Quantum Key Distribution (QKD) systems.

Drone-based Quantum Key Distribution (QKD) is a cutting-edge method for securely transmitting encryption keys using quantum mechanics, but with the added mobility of drones.

This collaboration aims to enhance secure telecom infrastructure using the BB84 protocol with polarization encoding, targeting Technology Readiness Level (TRL) 6 or higher.

Technology Readiness Level (TRL) 6 refers to a stage in technology development where a system or prototype has been validated in a relevant environment. This means it has moved beyond basic lab testing and is being tested in conditions that closely resemble real-world applications.

How It Works:

The drone based quantum communication system consists of a drone (left) that generates entangled photon pairs and distributes them to ground stations. From each pair, one photon (purple beam) goes directly to the ground, while the other (pink beam) is relayed through the second drone (right).

1. Quantum Key Distribution (QKD) ensures secure communication by using quantum properties to generate encryption keys that cannot be intercepted without detection.
2. Drones act as mobile quantum communication nodes, enabling secure key exchange over long distances, even in areas lacking traditional telecom infrastructure.

The system typically employs the BB84 protocol with polarization encoding, making it resistant to eavesdropping.

Why It Matters:

• Defense & Security: Enables encrypted communication for military and government operations.
• Emergency Response: Provides secure data transmission in disaster zones.
• Mobile Networks: Expands quantum-secure communication beyond fixed fiber-optic setups.

As part of the collaboration, C-DOT and Synergy Quantum will jointly pursue the development of quantum communications technologies optimized for drone-based deployment. The partnership will also include co-creation of research proposals for national and international grant applications and dissemination of outcomes through scholarly publications, white papers, and other platforms.

Key representatives from both organizations may also engage in delivering expert talks, short courses, and organizing symposia, conferences, and meetings on timely research themes.

The initiative aligns with India's Atmanirbhar Bharat vision, fostering indigenous innovation in quantum communication. The QKD systems will be optimized for drone-based deployment, making them valuable for defense, emergency services, and government networks.

C-DOT CEO Rajkumar Upadhyay emphasized the importance of merging public R&D with private innovation, while Synergy Quantum CEO Jay Oberoi highlighted India's potential to lead in drone-based quantum-secure communications.

This partnership could be a game-changer for secure mobile data transmission as it is expected to lay the foundation for next-generation quantum-safe telecom infrastructure, revolutionizing secure data transmission for applications in defence, emergency response, critical infrastructure, and secure government communication.
