India’s Quantum Push to Secure Digital Future
India is set to develop a cutting-edge quantum technology-driven network to safeguard its digital infrastructure and economy against escalating cyber threats. In an exclusive interview, Department of Science and Technology (DST) Secretary Prof. Abhay Karandikar announced plans to leverage quantum computing and communication for unbreakable encryption and secure data transmission.
Why Quantum Tech is Critical for India
Quantum computing operates on qubits, which outperform classical binary systems by solving complex problems exponentially faster. While this offers breakthroughs in fields like medicine and AI, it also poses risks: existing encryption could be cracked by quantum-powered hackers.
- Prof. Karandikar’s Warning: “Cyberattacks on AIIMS, CoWIN, and banks show our vulnerabilities. Quantum-resistant systems are no longer optional.”
- Global Race: China and the U.S. lead in quantum R&D; India’s ₹6,000 crore National Quantum Mission (2023) aims to close the gap.
Key Components of India’s Quantum Network
- Quantum Key Distribution (QKD): Hack-proof encryption for government and financial data.
- Secure Communication Infrastructure: Linking defense, healthcare, and banking systems.
- Domestic Quantum Ecosystem: Reducing foreign reliance via IITs, ISRO, and startups.
Challenges to Overcome
- Talent Shortage: Need for specialized physicists and engineers.
- Funding & Infrastructure: High costs of quantum hardware development.
- Strategic Collaborations: Partnerships with U.S. (iCET) and private players (TCS, Infosys).
Impact on India’s Economy & Security
- Finance: Secure UPI and banking transactions.
- Defense: Quantum-encrypted military communications.
- Citizen Data: Protection for Aadhaar and health records.
“Quantum dominance equals cyber sovereignty,” stressed Karandikar, framing this as a national security priority.
The Road Ahead
With trials underway and collaborations in place, India’s quantum network could launch pilot projects by 2025–aligning with its $1 trillion digital economy goals.
