India’s Quantum Leap: From Ancient Philosophy to Post-Quantum Cryptography
This article explores the evolution of quantum technology, focusing on India's National Quantum Mission and the global shift toward post-quantum cryptography. It bridges the gap between complex physics, national policy, and philosophical inquiry regarding the future of digital security.
Why it matters
As quantum computing advances, it threatens current encryption standards, making the transition to post-quantum security a critical global priority for national and digital infrastructure.
The rapid evolution of quantum technology is forcing a global rewrite of the rules of digital trust. The Hindu’s e-book, India’s Quantum Leap: From Ancient Philosophy to Post-Quantum Cryptography, offers a grounded, in-depth understanding of the realities of quantum hardware development, the pressing need for cybersecurity transitions, and the profound questions raised by modern physics.
Moving beyond the media hype of immediate quantum supremacy, this volume offers a sober look at the fundamental science behind qubits, superposition, and entanglement, and explores the long, challenging road to true quantum advantage. It unpacks India’s National Quantum Mission (NQM) and its pursuit of indigenous quantum processors and satellite-based communication. It details the formidable engineering hurdles of decoherence in today’s Noisy Intermediate-Scale Quantum (NISQ) devices. It also explains how the “Harvest Now, Decrypt Later” strategy and the looming threat of “Q-Day” are accelerating a global scramble towards post-quantum cryptography (PQC).
