The Quantum-Cryptographic Co-evolution

2026-04-02

AI Summary

This study addresses the existential threat posed by cryptographically relevant quantum computers (CRQCs) to current cryptographic infrastructure by proposing a “quantum-cryptography co-evolution” model. The model introduces a two-dimensional framework with cryptographic resilience on the horizontal axis and computational capability on the vertical axis, systematically delineating four quadrants of technological evolution. It formally characterizes, for the first time, the transition pathway from classical cryptography to quantum-resistant architectures, identifies the “quantum gap” as the paramount systemic risk, and articulates key challenges across each evolutionary stage. Through systematic modeling and risk analysis, this work provides a theoretical foundation for developing quantum-resilient migration strategies and advancing cryptographic agility in deployment.

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.
