Why in the news?

Recently, NITI Aayog's Frontier Tech Hub (NITI-FTH)released a strategic paper on "Quantum Computing: National Security Implications & Strategic Preparedness".

How Quantum computing is reshaping the National Security Paradigm

  • Cryptography and Cybersecurity: A powerful quantum computer could break widely used public-key encryption algorithmsforcing nations to adopt Post-Quantum Cryptography (PQC) (algorithms designed to resist quantum attacks) to safeguard their data.
    • E.g. The National Quantum Initiative Act of 2018 of the USA emphasizes national security through PQC to counter future cyber threats.
  • Enhanced Intelligence Gathering: Quantum computing could revolutionize intelligence analysis by processing vast, complex datasets beyond classical capabilities, enhancing intelligence to intercept, analyze, and decode communications at an unprecedented scale.
    • E.g. NATO's 2024 strategy calls for quantum-ready defense applications, including sensing, imaging, and securing communications through quantum-resistant cryptography.
  • Secure Communications: Such as Quantum Key Distribution (QKD) to distribute encryption keys between two parties with provable security.
    • E.g. China built the world's longest land-based (2,000 km) QKD network between Beijing and Shanghai that transmits sensitive data securely.
  • Military Hardware: Quantum technologies will drive breakthroughs in materials science, leading to next-generation military hardware. 
    • E.g. Quantum-enabled AI will power autonomous military drones and robotic systems, enhancing both offensive and defensive capabilities.
  • Economic Warfare: The ability to break encryption may destabilize financial markets, compromise banking and digital payment systems, creating new threats in economic security.
    • E.g. Initiatives like the National Quantum Initiative Act of USA highlights the need of quantum innovation for both economic and strategic security.
  • Geopolitical Power: Nations that achieve early breakthroughs in quantum computing will establish a technological and knowledge base that others will struggle to replicate.
    • For instance, China's Micius satellite (2016) enabled quantum-secured long-distance communication, showcasing its lead in quantum tech and secure networks.

Key Recommendations

  • Continuous Monitoring: Set up a dedicated quantum task force to track global tech progress and adversarial capabilities.
  • Cryptographic Intelligence: Conduct regular audits to identify quantum-related vulnerabilities in defense, finance, and critical infrastructure.
  • PQC Transition Plan: Implement a risk-prioritized roadmap with accelerated Proofs of Concept (POCs), testing, certification, and cross-sector info sharing for post-quantum cryptography adoption.
    • Such as Google Chrome's experiment with post-quantum algorithms like Kyber in real-world browser encryption.
  • Strengthening the Quantum Workforce: Initiate Quantum information science (QIS) education at higher education level, workforce training for the existing quantum workforce, and reform immigration for global talent.
  • Building a Quantum Ecosystem: Such as the US' Quantum Economic Development Consortium (QED-C); Japan's Quantum Strategic Industry Alliance for Revolution, whose primary focus is to enable and grow the quantum industry.
  • International Collaboration on Quantum with like-minded partners to coordinate QIS technology development, such as India and European Commission signed an "Intent of Cooperation on High Performance Computing (HPC), Weather Extremes & Climate Modeling and Quantum Technologies" in 2022.
  • Others
    • Early Warning System: Leverage scientific intelligence for potential breakthroughs.
    • Crypto Agility Framework: Issue clear directives to ensure organizations can swiftly adapt to quantum-era encryption changes or breakthroughs.
    • Flexible R&D Funding: Adapt investment priorities based on emerging breakthroughs.

Conclusion: With its transformative potential across defense, intelligence, and secure communications, quantum computing will be a cornerstone in India's journey toward strategic resilience and the vision of Viksit Bharat @2047.

Steps Taken by India in Quantum Technology

  • National Quantum Mission (NQM) (2023):  With aim to seed, nurture and scale up scientific and industrial R&D and create a vibrant & innovative ecosystem in Quantum Technology (QT). 
  • Quantum-Enabled Science and Technology (QuEST) program (2018): Initiated by DST, aimed at R&D activities via funding national quantum labs and developed infrastructure required to progress with developments in Quantum Technologies.
  • Quantum Academic Research and Innovation Hubs
    • IISc Bangalore, hosting a dedicated center focused on quantum algorithms, information theory, and error correction.
    • National Mission for Quantum Frontier, which trains students and researchers with skills essential for the quantum technology field.
    • IIT Madras, established Centre for Quantum Information, Communication and Computing (CQuICC).
  • Private Sector and Startup Contributions
    • QNu Labs, selected as one of the startups under NQM working to build and deploy the world's first end-to-end quantum- safe heterogeneous network.
  • Other
    • Quantum Communication Lab at C-DOT, Delhi and indigenously developed Quantum Key Distribution (QKD) solution by C-DOT.
