Quantum Country
An interactive introduction to quantum mechanics and quantum computing. A good place to understand where the capabilities of quantum computers come from and why they differ from classical machines.
Post-quantum cryptography knowledge base
Selected materials, standards, reports and tools that help you understand PQC and prepare for migration.
Fundamentals

Why quantum threats affect every organization
An explanation of why the problem is not limited to governments and the military: which data, communications and processes may lose protection once today’s cryptography stops being sufficient.

Understanding Quantum Technologies 2026 — Olivier Ezratty
An extensive compendium of quantum technologies: from physics and hardware, through algorithms and communication, to PQC, market and vendors. A good source when you need a broader picture of the whole ecosystem.
Migration
for CISOs
TNO — Post-Quantum Cryptography
A practical guide to preparing an organization for migration: from recognizing the cryptography in use to planning the successive stages of change.
for CISOs
NIST IR 8547 — Transition to Post-Quantum Cryptography Standards
Shows when and how NIST plans to move away from RSA, ECDH and ECDSA. Useful for setting deadlines, priorities and the migration horizon.
technical
NIST CSWP 39 — Considerations for Achieving Crypto Agility
Explains how to design systems so that cryptographic algorithms can be replaced without a costly rebuild of the entire environment. Useful where migration is meant to become the start of lasting crypto-agility.
Standards

NIST — Post-Quantum Cryptography
The official source of information on post-quantum cryptography standards: which algorithms are already approved and which are still being evaluated and developed.
standards
ECCG — Agreed Cryptographic Mechanisms
European guidelines on cryptographic mechanisms used in security certification. They also cover post-quantum algorithms and hybrid solutions.

BSI marks the end of classical asymmetric cryptography
What the German BSI says about moving away from RSA and ECC, which dates it points to, and what organizations should start preparing for the change.
Risk
for CISOs
Will quantum threats fit into the cybersecurity transformation
How to look at quantum risk together with other changes in cybersecurity: where real exposure appears, what can be threatened, and what determines the urgency of action.
for CISOs
Global Risk Institute — Quantum Threat Timeline
An annual review of expert opinions on when quantum computers may become capable of breaking today’s cryptography. Helps separate realistic estimates from media forecasts.
Reports & guidance
for CISOs
Poland’s Cybersecurity Strategy and post-quantum cryptography
An analysis of how Poland’s cybersecurity strategy approaches PQC and QKD, what it says specifically, and which questions it leaves open.
for CISOs
EU roadmap for the transition to post-quantum cryptography
The plan for EU Member States’ transition to PQC: starting the transformation by the end of 2026, securing the most important use cases by 2030, and as broad a transition to PQC as possible by 2035.
Tools / maps
PostQ.pl
PostQ Radar
Shows which Polish public and banking services already use post-quantum cryptography, and whether protection runs directly in the service itself or is provided by an intermediary, e.g. a CDN or cloud provider.
PostQ.pl
pq-map & pq-pulse
Open tools that help you see which services are publicly exposed, what cryptography they use, and which external components they depend on.

Post-Quantum Cryptography Alliance (PQCA)
An ecosystem of open projects supporting the adoption of post-quantum cryptography — from libraries and algorithm implementations to protocol integrations and testing tools.
