The preprint of our paper entitled “Automated Charge Transition Detection in Quantum Dot Charge Stability Diagrams” by Fabian Hader, Fabian Fuchs, Sarah Fleitmann, Karin Havemann, Benedikt Scherer, Jan Vogelbruch, Lotte Geck, and Stefan van Waasen is now available. Our Python package SimCATS-Datasets provides an even more straightforward way to use our simulation for your research! The package simplifies the creation and loading of large SimCATS datasets.

In the newest issue of the employee magazine "inside 3 | 2024" from Forschungszentrum Jülich, our colleague and team leader (System Modeling) Junior-Prof. Lotte Geck talks about her career.

From May 6th to May 10th 2024, Prof. Dr. Stefan van Waasen (head of ZEA-2 and professor at University of Duisburg-Essen) held for the fourth time an on-site lecture course, starting in 2017 in the frame of the Georgian-German Science Bridge (GGSB) , on "Measurement and Sensor Systems" for the students of the Electrical and Computer engineering program of the Agricultural and Free University of Georigia in Tbilisi.

Finally, the time has come: The result of our joint efforts over the past two years, our compact electronics and sophisticated crate composition embarked on its journey. Last Wednesday, it arrived at the Institute for Data Processing and Electronics (IPE) at the Karlsruhe Institute of Technology, ready for its final cut.

Quantum dots must be tuned precisely to provide a suitable basis for quantum computation. A scalable platform for quantum computing can only be achieved by fully automating the tuning process. One crucial step is to trap the appropriate number of electrons in the quantum dots, typically accomplished by analyzing charge stability diagrams (CSDs).

As part of the quantum computing initiative, QSolid, ZEA-2 is engaged in the development and testing of scalable cryogenic qubit control using optimized CMOS technologies. With the next cryogenic test setup, it is possible to speed up the characterization of cryogenic circuits down to 5 Kelvin. Leveraging two cryostats concurrently allows for parallelizing measurements leading to improved throughput and accelerated device characterization.

We are happy to announce that we will be again part of the Quanteen Day this year. Join us and other scientists for free online. You are interested in MINT / STEM? We are looking forward to get in touch with you. The event will be held in German.

Exciting times have come to an end! Our colleagues just concluded the Silicon Quantum Electronics Workshop in Kyoto, Japan. The Silicon Quantum Electronics Workshop is a series of workshops focusing on silicon-based approaches to quantum electronics. The 2023 edition (SiQEW 2023) was held Oct. 31 - Nov. 2, 2023 at the International Conference Center Kyoto. Lammert Duipmans, Patrick Vliex, Dennis Nielinger and Stefan van Waasen (Director of the ZEA-2 Institute) attended the SiQEW 2023.

Our enriching experience at IEEE Quantum Week 2023 in Bellevue, Washington has come to an end. Colleague Dennis Nielinger delivered a compelling invited talk on Cryogenic Electronics for Quantum Systems, drawing significant interest from industry partners and culminating in a dynamic and fruitful discussion. Engaging with peers from Fermilab, Microsoft, IBM, Google, and Intel, we explored our cryo-electronics approach for qubit control and gained valuable insights into their solutions and research related to operating CMOS at 4 Kelvin.

With the successful launch of the Atmospheric Coupling and Dynamics Explorer (ARCADE) satellite, an innovative remote sensing instrument from Forschungszentrum Jülich for atmospheric research has been sent into space. ARCADE is a small satellite with an edge length of 30 cm and carries as its main scientific payload a remote sensing instrument from Forschungszentrum Jülich equipped with a novel Spatial Heterodyne Interferometer (SHI). The interferometer was developed jointly with Forschungszentrum Jülich Institute of Energy and Climate Research – Stratosphere (IEK-7), the Central Institute of Engineering, Electronics and Analytics - Electronic Systems (ZEA-2) and numerous students from the University of Wuppertal.

In their pursuit of academic and professional growth, Mariam Papava and Ketevan Lomjaria, two exceptional students from the Agricultural University of Georgia (AUG) at Kakha Bendukidze Campus, started on an exchange program to broaden their understanding of electrical and computer engineering. With a strong drive to expand their knowledge as well as practical skills, they began a transformative journey that exposed them to cutting-edge subjects and provided them with invaluable experiences in a supportive as well as diverse academic environment at Electronic Systems Institute (ZEA-2) at Forschungszentrum Jülich. The two women stayed for one month and were able to gather many new and exciting impressions.

In the newest issue of the employee magazine "inside 2 | 2023" from Forschungszentrum Jülich, our colleague and team leader (IC Development) Dr. André Zambanini talks about his work at ZEA-2.

From April 24 to 28, 2023, Stefan van Waasen (Director of the ZEA-2 Institute at Forschungszentrum Jülich and Profesor at Universität Duisburg-Essen) was in Georgia at the Agricultural University of Georgia (AUG) at Kakha Bendukidze Campus.

Forschungszentrum Jülich’s research magazine effzett has received three awards. Within the scope of the International Creative Media Award (ICMA), effzett issue 3/2021 and effzett issue 1/2022 received one award each in the categories “cover story”, “magazines online”, and “magazines print”.

The Tag der Neugier 2022 on Sunday, August 21, was a great success: Around 20,000 visitors came to the research center in sunny weather and explored the Jülich campus. At more than 300 decentralized presentations, they were able to learn about Jülich's research, experience science for themselves on site, and also find out about career opportunities here at the FZJ. Colorful entertainment with research shows, music and much more was offered by a seven-hour non-stop program at the lake stage at the Seecasino.
