ITS blog: News in the field of post-quantum cryptography – December 2025

We bring you a regular batch of news from the field of post-quantum cryptography. What major events took place in the last weeks of 2025? Take a look with us and stay up to date!

November 2025 brought further steps in the long-term transition to quantum-resistant technologies in Europe. Although we are only halfway there, policy and practice are slowly moving from the theoretical level to concrete plans. Here is a selection of the most important events and trends that security teams, IT managers, and cyber specialists should not overlook.

Strategic coordination in the EU: public consultation for the "Quantum Act"

The European Commission has launched a public consultation as part of the preparation of a new legal framework, the "EU Quantum Act, " which aims to create a more comprehensive legislative environment for quantum technologies, including post-quantum cryptography. The consultation took place during November and gathered feedback from industry, academia, and other stakeholders. This step represents a shift from previous strategic recommendations to the possibility of specific regulatory commitments at the European level. The consultation will influence the final form of the draft law, which is expected to be released next year.

Roadmap for transition to PQC: preparations for implementation continue

Against the backdrop of legislative measures, work is still ongoing on a coordinated implementation roadmap for the transition to post-quantum cryptography, which is being prepared by a working group within the NIS Cooperation Group. This document links European strategic objectives with practical milestones for Member States and critical infrastructure operators and serves as a reference framework for the transition to resilient cryptographic systems. Its elements and recommendations have already been published during the year and are now being synthesized with comments from the November consultation.

Conferences and European initiatives

Přestože hlavní European Conference on PQC Migration proběhne až začátkem prosince, přihlášky a příprava programu byly v listopadu uzavřeny. Tato dvoudenní odborná akce se zaměří na praktické aspekty přechodu na post-kvantovou kryptografii – od analýzy rizik a inventarizace kryptografických aktiv až po diskuse o hybridních přístupech a koordinaci mezi členskými státy. Akce je organizována společně francouzským, německým a nizozemským národním úřadem pro kybernetickou bezpečnost a dalšími partnery a podtrhuje rostoucí význam technické i politické spolupráce v EU. Plánujeme se aktivně zúčastnit a přineseme vám z akce podrobnější report.

Quantum Day 2025

Za zmínku stojí v rámci prosince akce Quantum Day 2025, třetí ročník akce pořádané pod záštitou ČVUT a IBM, jež v rámci jednoho dne spojil přední odborníky v kvantovém počítání, akademiky, nadějné studenty i zástupce průmyslu. Jaké jsou predikce vývoje, jakých zajímavých výsledků se již v kvantové oblasti dosáhlo na české půdě, či jak funguje projekt Quantum Innovation Center Czech Republic – to a mnoho dalšího bylo předmětem nabitého dne, jež proběhl 2. prosince v Betlémské kapli.

Trends and recommendations: what to take away

The end of the year once again confirms that the transition to post-quantum cryptography is not a matter of a single upgrade —it is a coordinated process that combines:

strategies and legal frameworks at EU level,
technical documentation and roadmaps to be implemented by Member States in their national plans,
community involvement and professional events for sharing experiences and best practices.

As with the aforementioned documents and initiatives, they emphasize the need for early preparation and a pragmatic approach to inventorying cryptographic assets, risk analysis, and pilot testing of hybrid and fully post-quantum solutions.
