QUANTUM MAGAZINE – ISSUE #3 (MAY 2026)
The Magazine for Quantum Tech
SPECIAL FEATURE: Post-Quantum Cryptography
Issue #3 delivers an authoritative special report on post-quantum cryptography (PQC) — the global effort to replace the world’s vulnerable encryption before a cryptographically relevant quantum computer arrives. This comprehensive feature explains why “harvest now, decrypt later” attacks make the migration urgent today, even though no machine capable of breaking RSA yet exists, and lays out the practical roadmap organisations must follow to reach quantum safety.
The feature includes:
- The Quantum Threat Explained: Why Shor’s algorithm collapses RSA and elliptic-curve cryptography from infeasible to tractable, why symmetric encryption survives, and what is actually at risk across digital trust infrastructure
- Harvest Now, Decrypt Later: Analysis of the store-now-decrypt-later threat model and Mosca’s inequality — the arithmetic security planners now use to determine whether they are already too late
- Industries in the Blast Radius: Sector-by-sector examination of exposure across finance and banking, government and defence, healthcare and medical devices, telecommunications and IoT, cloud and data storage, and automotive and transportation
- Inside the New Algorithms: A close look at the post-quantum families — lattice-based, hash-based, code-based, multivariate and isogeny-based cryptography — and why algorithmic diversity is a deliberate risk-management decision
- Standards & Migration: Coverage of the NIST standardisation process, the four-phase migration roadmap, crypto-agility as a design principle, and South Korea’s national PQC pilot as a template for critical-infrastructure conversion
- PQC vs. QKD: How post-quantum cryptography and quantum key distribution differ, and why leading vendors combine the two for defence-in-depth assurance
- Company Profiles: Detailed analysis of dedicated quantum-safe providers
