Science & Technology
India’s First QKD over Multi-Core Fibre — C-DOT & STL
C-DOT (New Delhi; DoT, MoC) and STL (Sterlite Technologies, Pune; MD: Ankit Agarwal; est. 1988) achieved India’s first Quantum Key Distribution (QKD) transmission over a 4-core Multi-Core Fibre (MCF), with a stable link spanning more than 100 km. Quantum signals used one core; the other three carried classical high-speed data. C-DOT’s QKD systems have received Technology Approval from TEC, DoT.
Sports & Anti-Doping
India’s APMU — 17th Country with Athlete Passport Unit
India’s Athlete Passport Management Unit (APMU) was inaugurated at NDTL, New Delhi by Union Minister Dr. Mansukh Mandaviya, making India the 17th country globally with this facility. The ABP (Athlete Biological Passport) programme longitudinally tracks blood parameters and hormonal levels to detect doping patterns without directly identifying banned substances. WADA introduced ABP Operating Guidelines effective December 1, 2009.
Governance & Digital
DBT Savings — Rs 3.48 Lakh Crore via JAM Trinity
A BlueKraft Digital Foundation (New Delhi) assessment (MoF-supported) found India’s DBT (Direct Benefit Transfer) system saved Rs 3.48 lakh crore (2009–2024) by minimising welfare leakages. Subsidy spending halved from 16% to 9% of total government expenditure. The system is powered by the JAM Trinity: Jan Dhan + Aadhaar + Mobile.

Economy
Fitch — India FY26 at 6.4%; Global Below 2% (2009-Level Low)
Fitch Ratings revised India’s FY26 GDP to 6.4% (−10 bps); FY25 to 6.2% (−10 bps); FY27 retained at 6.3%. Global growth projected below 2% in 2025 — the weakest since the 2009 financial crisis (excluding pandemic years). Fitch cut global growth by 0.4 pp (China and US each −0.5 pp). Drivers: global trade tensions and US tariff policy uncertainty.
Health & Medical
Dr. Mathew Samuel Kalarickal — Father of Angioplasty in India
Dr. Mathew Samuel Kalarickal (b. January 6, 1948, Kottayam, Kerala; d. April 2025, Chennai, age 77) performed India’s first coronary angioplasty in 1986. Awards: Dr. B.C. Roy Award (1996), Padma Shri (2000), Honorary D.Sc. from TN Dr. MGR Medical University (2003).

Think & Discuss
Quantum Secure Communication: Is India Building the Right Foundation for Cybersecurity in the Quantum Age?
Context from today’s quiz: C-DOT and STL achieved India’s first Quantum Key Distribution (QKD) transmission over a 4-core Multi-Core Fibre spanning more than 100 km — a significant step toward building quantum-secure communication infrastructure. QKD enables cryptographically secure key exchange based on the laws of quantum mechanics, making it theoretically impossible to intercept without detection. This development aligns with India’s National Quantum Mission (NQM), which has earmarked Rs 6,003 crore for quantum technologies.
🤔 Your Perspective Matters
Quantum communication represents one of the most consequential technology frontiers of the coming decade. Nations that build quantum-secure infrastructure will be able to protect sensitive government, military, and financial communications from the threat of quantum computers — which are expected to eventually break current encryption standards. India’s QKD milestone places it alongside the USA, China, and European powers in this race. But the gap between laboratory demonstrations and nationwide deployment remains vast.
How strategically urgent is quantum communication for India — and does India have the talent, investment, and institutional ecosystem to build quantum-secure infrastructure at a national scale within a meaningful timeframe?
How strategically urgent is quantum communication for India — and does India have the talent, investment, and institutional ecosystem to build quantum-secure infrastructure at a national scale within a meaningful timeframe?
- China has already deployed the world’s longest quantum communication network (over 4,600 km), integrating satellite-based QKD with ground infrastructure. How significant is India’s 100 km MCF-based QKD milestone relative to this global benchmark, and what would a realistic roadmap look like for India to scale to national infrastructure?
- The most immediate threat from quantum computers is to existing public-key encryption (RSA, ECC), which secures virtually all internet communications. Should India prioritise quantum-resistant cryptography (post-quantum encryption) as a faster and more scalable security upgrade, while quantum networks are built over the longer term?
- India’s National Quantum Mission has set ambitious targets, but quantum talent remains concentrated in a handful of IITs and research institutions. What structural investments — in quantum education, industry-academia collaboration, and global research partnerships — does India need to sustain momentum beyond early demonstrations?
