Congratulations to Prof. Dr. Carsten Schuck, David Lemli, Tim Buskasper and Lukas Schulte for breaking the Guinness World Record (GWR) for the Smallest QR Code! The tiny QR code, spanning only 5.38 square micrometres, is seven times smaller than a human red blood cell and about 20 times smaller than the previous world record. It was fabricated to promote the cleanroom lab course Foundations of Nanofabrication, part of our teaching program, and aims to inspire interest in nanofabrication among physics students.

This impressive achievement was made possible through the efforts of our research group, in partnership with the Münster Nanofabrication Facility (MNF), which, as part of the University of Münster, provides students with access to cutting-edge nanotechnology.

We would like to thank Hitachi High-Tech Europe GmbH in Krefeld, for serving as an independent surveyor to ensure unbiased measurement of the QR code following GWR guidelines.

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 the teaching program of Prof. Schuck. 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!

QU-PIC 1st Consortium Meeting

Representing the Schuck group, David showcased his advancements in integrating SNSPDs on Al2O3 waveguides at the Qu-PIC consortium meeting in Berlin, held on 11-12 September 2024. This two-day event at Technische Universität Berlin brought together key academic and industry partners to advance photonic integrated circuits for quantum technologies in Europe. The consortium aims to establish a robust European supply chain for future quantum systems.

Academic partners:
University of Twente, Ghent University, University of Münster, Chalmers University of Technology, Technische Universität Berlin, Physikalisch-Technische Bundesanstalt (PTB)

Industry partners:
QuiX Quantum, Tematys, TOPTICA Photonics, TOPTICA EAGLEYARD, ALUVIA, VLC Photonics (Hitachi Group)

QT.Roadmapping

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!

AGPP Teaching Award

Congratulations to Adrian and Paul (now with Prof. Heusler) on winning the Teaching Award of the Working Group Undergraduate Physics Laboratory (Arbeitsgruppe Physikalische Praktika, AGPP) of the German Physical Society (DPG) together with our colleagues at the Institute of Physics Education, the Institute of Physics and the Hamburg University of Applied Sciences for our joint work on the MiReQu-Project, allowing students to experience entanglement and it's use in quantum key distribution through augmented reality environments.

Photo-Chemical Activation Functions for Neural Networks

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.
