Check out the October issue of wissen|leben, where the cleanroom lab course offered to physics master’s students is highlighted. The article provides a fascinating glimpse into the hands-on experience gained during the Foundations of Nanofabrication course, part of our teaching program. Students work in the Münster Nanofabrication Facility (MNF), creating nanometer-scale materials like OLEDs in cleanroom conditions. The piece details how the lab course enhances students' understanding of nanotechnology and practical skills with advanced equipment. Text available in German only!

Our research group is excited to join the MANTIS project, aiming to protect critical infrastructures such as gas pipelines from cyberattacks using quantum encryption. The project, led by Fraunhofer IOF and funded by the Federal Ministry of Education and Research (BMBF), will run until 2027.

For more details, see the University of Münster press release and the Fraunhofer IOF press release.

The Ministries of Culture and Science (MKW) and of Economic Affairs, Industry, Climate Action and Energy (MWIKE) have kicked off a Roadmapping process for developing Quantum Technologies in North Rhine-Westphalia, which will be lead by our colleagues from the Fraunhofer Institute for Laser Technology (ILT) and coordinated by the newly established office QT.NMWP.NRW. We are excited to contribute to the process!

Check out the November edition of the Physik Journal with a focal section on quantum computing. Among very nice contributions from Jens Eisert, Frank Wilhelm-Mauch, and an interview with Heike Riel,  Emma Lomonte from Xanadu, Wolfram Pernice from Heidelberg University and Carsten Schuck write about photonic quantum computing (German only, registration required).

On November 1st we kick-off the QuGrids-Project with our partners at the Forschungszentrum Jülich (FZJ), the RWTH Aachen and the Fraunhofer FIT. The project aims to establish a profile in using quantum technologies for designing, optimizing and securing energy grids for a more sustainable future. We were happy to receive generous funding from Minister Ina Brandes at the Ministry of Culture and Science of the State of North Rhine-Westphalia.

Our joint work with the AG Risse and the AG Ravoo on using Azobenzene-based Photo-Chemical Activation Functions in Optical Artificial Neural Networks is now published in Advanced Intelligent Systems! We use a physically motivated model and obtain a tuneable yet interpretable activiation function that enables solving classification tasks such as XOR, Circle, MNIST and FashionMNIST with a neural network. This is an important stepping stone for understanding Intelligent Matter.

The European Quantum Technology Community meets at EQTC in Hannover to discuss progress, perspectives and transfer of research and recent developments in the field. Alejandro and Carsten will present work in our European projects ESSENS and SURQUID.

The Münster Nanofabrication Facility (MNF) will hold its annual MNF-Day on November 7th at CeNTech.

North Rhine-Westphalia strengthens Education, Innovation, and Networking (EIN) in quantum technologies. The University of Münster is among the twelve founding members of the "EIN Quantum NRW" network, which counts with strong endorsement from Hendirk Wüst, Minister-President of North Rhine-Westphalia as well as the Ministry of Culture and Science and the Ministry of Economics, Innovation, Digitization, and Energy.

Today is the International Day of Women and Girls in Science, featuring Lisa, who is currently holding an INSPIRE Potentials SPIN Master’s fellowship, speaking about her experience in science.

We are very happy to be selected for one of the U Twente - WWU Münster Collaboration Grants with our partner Prof. Pepijn Pinkse at MESA+ and the Faculty of Science and Technology in Twente!
We will be working on a new international Quantum Key Distribution Link between our universities using modern nanophotonic chips with superconducting nanowire single photon detectors.
Also, many congrats to our colleagues on both sides of the border for their exciting  UT-WWU Collaboration Grant proposals!

Our proposal for a Millikelvin-Microwave-Photonic Probestation was selected for funding in the German Research Foundation's (DFG) Quantum Communication Development Environment (QCDE) call within the Major Instrumentation Initiative. Most credit goes to Prof. Hubert Krenner, who coordinated the proposal. We are looking forward to working with AGs Krenner, Bratschitsch and Wurstbaueron this exciting project!

Alex and Tobias report the integration of colloidal quantum dots with nanophotonic waveguides in ACS Photonics with contributions from the AG Bratschitschand AG Pernice. They managed to both excite the quantum dots and collect single fluorescence photons via Ta₂O₅-on-insulator waveguides and report on how the approach can be scaled to larger system size.
