On 23 February 2026, the IQST community gathered at the Karlsruhe Institute of Technology (KIT) for IQST Day 2026. Hosted in the Gaede Lecture Hall, the event brought together more than 200 participants from across academia and the broader quantum ecosystem for a full day of scientific exchange, discussion, and networking.
The day began with welcome remarks by IQST Directors Stefanie Barz and Fedor Jelezko, joined by Ina Schaefer, Vice Provost Research at KIT. In their opening addresses, they emphasized the importance of interdisciplinary collaboration and the growing strength of the quantum landscape in Baden-Württemberg and beyond.
The scientific program featured an outstanding lineup of internationally renowned invited speakers. Costanza Toninelli (INO-CNR / LENS, Italy) opened the first session with insights into quantum interfaces based on single molecules, followed by Julian Schmitt (Heidelberg University, Germany), who explored new frontiers in quantum matter made of light.
In the second session, Ian Walmsley (University of Oxford, United Kingdom) presented perspectives on shaping the quantum future, before Carsten Rockstuhl (KIT) delivered an IQST Fellow talk on designed and inversely designed quantum nanophotonic systems.
After lunch and the first poster interactions, the afternoon continued with Klaus Blaum (Max Planck Institute for Nuclear Physics, Germany), who discussed advances in quantum metrology using Penning traps, and Halina Rubinsztein-Dunlop (University of Queensland, Australia), who showcased optically controlled quantum sensors.
The final session highlighted further IQST Fellow contributions: Alexander Kühne (Ulm University), Patrick Emonts (Ulm University), and Julian Berberich (University of Stuttgart) presented their latest research spanning molecular quantum applications, tensor networks, and quantum algorithms.
A group picture during the afternoon coffee break captured the strong sense of community before the event concluded with an extended poster session and networking reception. The poster session once again proved to be a central element of IQST Day, fostering lively discussions between senior researchers, fellows, doctoral candidates, and industry representatives.
IQST Day 2026 marked the first time that KIT hosted this flagship IQST event, underlining the growing collaboration within the network and the shared commitment to advancing quantum science and technology through interdisciplinary exchange.
We thank all speakers, fellows, contributors, and participants for making IQST Day 2026 a dynamic and inspiring success.

Inside the Lab: IQST Early-Career Training Visit @Heidelberg
As part of the Early-Career Training Activities supported by the
IQST Graduate School @QuantumBW, the IQST Visit @Heidelberg
brought students and early-career researchers to the European Institute for
Neuromorphic Computing (EINC) for an afternoon of scientific exchange, hands-on
training, and networking.
The visit opened with a series of scientific talks highlighting current research
and innovation at the interface of quantum photonics and technology. Contributions
included a presentation on fiber-to-chip interconnects and reconfigurable photonic
circuits by J. Brandes, insights into superconducting nanowire single-photon detectors
and their applications by S. Ferrari, and a startup-focused talk by R. Bankwitz from
Linq Photonics, offering perspectives on the transition from academic
research to entrepreneurship.
A central element of the visit was the Pernice Lab tour, during which
participants rotated through five hands-on stations featuring live demonstrators.
These covered integrated photonic device characterization, fiber tapering using a
hydrogen flame, characterization setups for superconducting films and SNSPDs, active
fiber-to-chip alignment using a Fineplacer system, and a convolution-based neuromorphic
edge detection system. The interactive format enabled direct exchange with researchers
and provided valuable insights into experimental techniques and infrastructures.
The visit concluded with informal networking over refreshments, fostering discussions
across disciplines and institutions.
IQST warmly thanks the Pernice Lab and the entire hosting team in
Heidelberg for their openness, excellent organization, and commitment to early-career
training.

IQST Graduate School @QuantumBW: Three Days of Science, Skills, and Industry Insights
The IQST Graduate School @QuantumBW successfully ran a three-day program from 1–3 December 2025, bringing together its first international cohort of doctoral researchers, academic supervisors from across Baden-Württemberg, and representatives from the regional quantum industry. The event gathered participants from six countries across four continents and showcased strong links between academic research and local industry.
Day 1 – Project Presentations and Scientific Exchange
The meeting opened with welcome remarks by Prof. Dr. Stefanie Barz, Director of IQST, and continued with a full day of scientific exchange. Academic supervisors from five Baden-Württemberg universities — University of Stuttgart, Ulm University, Heidelberg University, University of Tübingen and University of Freiburg — presented the newly funded Graduate School projects.
A highlight of the day was the tutorial talk by Dr. Susanne Baumann (University of Stuttgart), titled “Controlling Individual Magnetic Spins on the Atomic Scale.” Project presentations by the academic supervisors were followed by a lively poster session, where PhD students presented their research plans, early results and internship timelines and engaged directly with supervisors and industry guests. Representatives from ten industry partners — active across the Baden-Württemberg quantum ecosystem and hosting student internships — also participated in the day’s discussions.
Day 2 – Early Career Training: Scientific Presentations Workshop
Day 2 launched the Graduate School’s Early Career Training series (open to IQST students and early career researchers across the region) with an interactive workshop led by Prof. Dr. Matt Carter (Williams College): “Scientific Presentations: How to Optimize Posters and Talks.”
Core principles of effective scientific communication

Designing clear, impactful visual slides
Presenting with confidence
Poster formats and practical alternatives
Participants worked through practical exercises, received peer feedback, and refined their presentation and poster skills in hands-on sessions.
Day 3 – Industry Visit: Swabian Instruments
The final day featured a visit to Swabian Instruments in Stuttgart-Zuffenhausen. The program included a company presentation and an introduction to time-tagging technology, followed by a networking lunch with company staff where students and employees exchanged views on careers and industry transitions. The visit continued with a guided tour of R&D and production areas and concluded with a practical, hands-on session using the Time Tagger API.

IQST at Quantum Effects 2025: Showcasing Quantum Innovation and Collaboration
The IQST team successfully took part in Quantum Effects 2025 in Stuttgart, presenting a broad spectrum of quantum research and technology integration from its partner institutions. At the IQST booth, researchers and graduate students engaged with visitors, demonstrating hands-on setups and sharing insights into ongoing projects in
quantum sensing, quantum computing, quantum networks, and quantum technology integration.
A special highlight was the presentation delivered by Jan Pusskeiler and Dennis Rieger, showcasing a collaborative project between the IQST Graduate School @QuantumBW and Qinu, an industry partner based in Karlsruhe. Their demonstration attracted great interest from visitors and exemplified the strong link between academic research and industrial innovation fostered within IQST.
In addition, the booth was visited by the Regionalräte, who had time to learn how IQST advances the quantum ecosystem of Baden-Württemberg both locally and internationally.
The booth also featured a social area, where visitors and participants could meet over an espresso, exchange ideas, and connect with members of the quantum community. All
students of the newly established IQST Graduate School @QuantumBW actively contributed to the booth, presenting their research and engaging with the public throughout the event.
Throughout the two days, IQST members fostered exchange across disciplines and institutions, strengthening connections within the quantum ecosystem and raising visibility for the vibrant research community in Baden-Württemberg.
A warm thank-you goes to all contributors — researchers, students, and staff — and to the visitors who took the time to engage with our team and explore the exciting work being done at IQST.
