Quantum Apocalypse: Fortifying Critical Infrastructure in the Age of Cyber Warfare by Sapann Harish Talwar
Quantum computing is no longer a future concept. It is becoming a reality that brings both breakthroughs and significant cybersecurity risks. This paper explores what experts are calling the “Quantum Apocalypse,” a future scenario where quantum computers have the power to break today’s encryption methods. If left unaddressed, this could lead to the mass decryption of sensitive data and a collapse of digital trust across critical infrastructure.
Key insights from the paper include:
Quantum algorithms such as Shor’s and Grover’s threaten current cryptographic systems like RSA, ECC, and DSA.
Critical infrastructure sectors such as energy, finance, healthcare, transportation, and defense face high risk.
Post-Quantum Cryptography (PQC) solutions are being developed, with NIST selecting CRYSTALS-Kyber and CRYSTALS-Dilithium as leading standards.
A phased roadmap is essential. This begins with cryptographic asset discovery, then building cryptographic agility, implementing PQC algorithms, and eventually retiring legacy systems.
Regulatory bodies across the world, including in the United States, the European Union, and India, are initiating quantum security frameworks.
A quantum-safe future will depend on hybrid encryption systems, quantum key distribution, and stronger collaboration between public, private, and academic sectors.
This outlines practical steps for governments, CISOs, and enterprise leaders to future-proof digital systems and ensure national security in the age of quantum threats.
