“The Time to act is now!” – First User Conference successful:
Under the motto “Securing Enterprise Communications,” around 70 participants from industry, politics, and research – including Europe’s leading experts in quantum-secure encryption – gathered on 16 and 17 October 2025, at the seQUcom user conference in the Frankfurt Union Hall to discuss the threat posed by Quantum and AI Technologies, regulatory developments, and concrete solutions such as Post-Quantum Cryptography (PQC) and Quantum Key Distribution (QKD). The focus was on the question of what will happen when Quantum Computers crack today’s common encryption algorithms, and how companies can make their communications quantum-secure today. The event was organized by KEEQuant GmbH, the Physikalisch-Technische Bundesanstalt (PTB), the Verband der Elektrotechnik Elektronik Informationstechnik (VDE), the Deutsche Industrieverbund für Quantensicherheit (DIVQSec), the management and technology consultancy BearingPoint, and Quantum Optics Jena GmbH. Representatives from the umbrella project for Quantum Communication in Germany (SQuaD) were also involved in the organization.
The two-day event was divided into two segments. On the first day, the Executive Track featured presentations by, among others, Dr. Felix Wissel (Deutsche Telekom Geschäftskunden GmbH), Christoph Graebnitz (Fraunhofer-Institut für Angewandte und Integrierte Sicherheit (AISEC)), and Dr. Heike Riel (IBM), who impressively demonstrated that the so-called Q‑Day – the day when Quantum Computers can break classical encryption algorithms – is closer than many think. Exciting presentations and lively discussions following contributions from Dr. Ulrich Seyfarth (BearingPoint), Daniel Groß (Bundesagentur für Arbeit), and Thomas Kraus (Deutsche Bundesbank) on topics such PQC, QKD, and the role of AI made one thing clear: action is needed now. Dr. Helmut Grießer (ADVA Network Security) and Dr. Kevin Fürchsel (Quantum Optics Jena GmbH) then outlined two different approaches for how companies can effectively address the threat posed by Quantum Computers. The first day concluded with a panel discussion on the steps necessary to prepare for Q‑Day. Thomas Lebeth (dacoso GmbH) subsequently picked up the topic and demonstrated what possibilities quantum-secure network encryption already offers and what measures companies can take today to prepare for the future.
On the second day, the Technical Track focused on practical implementation – that is, how the migration to PQC or QKD can be successfully achieved in practice. Use cases and contributions, including those related to standardization, were central topics. In two showcase presentations, Robin Boehn (Deutsche Telekom Technik GmbH) as well as Dr. Maja Kierdorf and Martin Zauchner (BWI GmbH) presented current solutions. In addition, short pitches by the industry exhibitors Quantum Optics Jena GmbH, KEEQuant GmbH, BearingPoint, and QuKommIn provided insights into ongoing developments. Following this, Prof. Dr.-Ing. Christof Paar (Max-Planck-Institut für Sicherheit und Privatsphäre) delved deeper into PQC and standardization topics, before Nicolas Perlot (Fraunhofer-Institut für Nachrichtentechnik, Heinrich-Hertz-Institut (HHI)) presented data transmission within the framework of the QuNET initiative. Dr. Daniel Minder (evolutionQ GmbH) addressed aspects of hybridization, crypto-agility, and symmetric key infrastructure, after which Mathias Kaschel (IMS Chips) concluded by presenting use cases of integrated photonics for Quantum Applications.
After two intensive days filled with strategic discussions and in-depth technical insights, there was no doubt about the central message of the event: the threat posed by Quantum Computers is real, and the time to react is rapidly running out. Taking action is the only way to maintain control over sensitive data. For this reason, the following applies: act now – the future of secure communication begins today!
