Four world-leaders are joining forces for pushing the realisation of quantum computers and their integration in HPC systems forward: Forschungszentrum Jülich, Goethe-University Frankfurt, ParTec and Quantum Machines have partnered for developing a 10+ superconducting qubit system and integrating it into the supercomputing infrastructure of the Jülich Supercomputing Centre.

A team of researchers from the 5th Institute of Physics at the University of Stuttgart is making important progress in the field of quantum simulation and quantum computing based on Rydberg atoms by overcoming a fundamental limitation: the limited lifetime of Rydberg atoms. Circular Rydberg states are showing enormous potential for overcoming this limitation. The renowned journal Physical Review X reports on this in its latest issue.

Researchers from Jena, Würzburg and Potsdam have successfully developed a design for the smallest system of its kind so far to take highly secure quantum communication to space: Led by Fraunhofer IOF, the project CubEniK developed an ultracompact payload for a satellite the size of a shoe box, a so called “CubeSat”. The goal of the mini satellite is to transmit a secure quantum key over a distance of 300 kilometers between two ground stations in Jena and Munich.

The Center Nanoelectronic Technologies (CNT) at Fraunhofer IPMS has recently acquired new cryostats for the research on qubits and the qualification of superconducting systems. The cryogenic measuring devices, which are particularly useful for analyzing quantum systems, are now in full operation. The provision of the equipment was funded by the Saxon State Ministry for Science, Culture and Tourism (SMWK).

Recently, the ALPHATRAP group around Sven Sturm in the division of Klaus Blaum at the Max Planck Institut für Kernphysik (MPIK) in Heidelberg measured the g factor of hydrogen-like tin ions on a precision level of 0.5 parts per billion. That is like measuring the distance Cologne-Frankfurt with a precision down to the thickness of a human hair This is a stringent test of QED for the simplest atomic system just like conventional hydrogen but with a much higher electric field experienced by the electron due to the charge of 50 protons inside the tin nucleus.

Single Quantum is proud to announce the expansion of its operations with the opening of Single Quantum Germany, a new office based in Stuttgart, one of Europe’s foremost centers for quantum research and technology. This move represents a significant step in their continued growth and commitment to providing world-class single photon detection solutions to both their current and future customers.

Fraunhofer IAO, Fraunhofer IPA and the IAT of the University of Stuttgart are pooling their research expertise to set up the cross-institute Fraunhofer Lab “flaQship”. The lab focuses on applied quantum computing in Stuttgart and Heilbronn.

The ability to conduct heat is one of the most fundamental properties of matter, crucial for engineering applications. Scientists know well how conventional materials, such as metals and insulators, conduct heat. However, things are not as straightforward under extreme conditions such as temperatures close to absolute zero combined with strong magnetic fields, where strange quantum effects begin to dominate. This is particularly true in the realm of quantum materials. Researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), University of Bonn, and Centre national de la recherche scientifique (CNRS) now exposed the semimetal zirconium pentatelluride (ZrTe5) to high magnetic fields and very low temperatures. They found dramatically enhanced heat oscillations caused by a novel mechanism. This finding challenges the widely held belief that magnetic quantum oscillations should not be detectable in the heat transport of semimetals, as the scientists report in the journal PNAS.

QC Design has achieved a GPU-acceleration breakthrough in Plaquette, its state-of-the-art software for designing and optimizing fault tolerance architectures. By collaborating with NVIDIA to integrate the NVIDIA cuQuantum SDK, Plaquette now leverages the cuTensorNet library to perform high-performance, full-state simulations of fault-tolerant quantum circuits. This advancement dramatically enhances fault-tolerant design, enabling simulations at unprecedented scale and performance.

From 2035, the Einstein Telescope will be able to study gravitational waves with unprecedented accuracy. For the telescope, researchers from Jena have manufactured highly sensitive sensors made entirely of glass for the first time.
