The Quantum-Cryptographic Co-evolution

Cryptography and Security 2026-04-23 v2

Abstract

As quantum computing matures toward the realization of Cryptographically Relevant Quantum Computers (CRQC), global cryptographic infrastructure faces an existential threat. This paper introduces a two-dimensional coordinate system to map the co-evolution of cryptographic resilience (x-axis) and computational capability (y-axis). By analyzing the four resulting quadrants, we categorize the transition from legacy classical systems to quantum-resilient architectures. We argue that the "Quantum Gap" - the delta between CRQC arrival and quantum-safe adoption represents the highest systemic risk, necessitating an immediate transition to crypto-agile frameworks.
