Overview
The Centre for Development of Telematics (C-DOT), India's premier telecom R&D institution under the Department of Telecommunications, unveiled 14 indigenous quantum products during its 43rd Foundation Day celebrations. These products focus on Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC) technologies to secure India's communication infrastructure against emerging quantum-era threats.
Key Quantum Technologies Developed

Critical Quantum Hardware Components
- C-SPD: Single-Photon Detector for detecting single-photon signals
- C-RD: Wideband RF Driver for intensity and phase modulators
Understanding Quantum Technologies
Quantum Key Distribution (QKD)
- Uses quantum mechanics principles to securely generate and distribute encryption keys
- Based on the observer effect and no-cloning rule: any interception disturbs quantum particles, alerting users
- Requires specialized quantum communication infrastructure
Post-Quantum Cryptography (PQC)
- Uses classical mathematical algorithms to resist quantum computer attacks
- Can be implemented on existing communication networks
- Incorporates NIST PQC algorithms
Comparison: QKD vs PQC
| Aspect | QKD | PQC |
|---|
| Foundation | Quantum mechanics | Classical mathematics |
| Infrastructure | Specialized quantum networks | Existing networks |
| Function | Key generation/distribution | Encryption algorithms |
