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.

Kipu Quantum, a leader in application and hardware-specific quantum computing solutions, announces that its Iskay Quantum Optimizer, a function available on Kipu’s PLANQK platform, is now available for use through IBM’s Qiskit Functions Catalog.

Physicists at the University of Cologne have taken an important step forward in the pursuit of topological quantum computing by demonstrating the first-ever observation of Crossed Andreev Reflection (CAR) in topological insulator (TI) nanowires. This finding, published under the title ‘Long-range crossed Andreev reflection in topological insulator nanowires proximitized by a superconductor’ in Nature Physics, deepens our understanding of superconducting effects in these materials, which is essential for realizing robust quantum bits (qubits) based on Majorana zero-modes in the TI platform — a major goal of the Cluster of Excellence ‘Matter and Light for Quantum Computing’ (ML4Q).

Physics has a problem – their key models of quantum theory and the theory of relativity do not fit together. Now, the German Research Foundation is funding physicist Dr. Wolfgang Wieland from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) as part of the Heisenberg Program to develop an approach that reconciles the two theories in a problematic area. A recently published paper that was published in the Journal “Classical and Quantum Gravity” gives hope that this could work.

Today, physicists are still asking themselves whether quantum mechanics needs hypercomplex numbers. FAU researchers Ece Ipek Saruhan, Prof. Dr. Joachim von Zanthier and Dr. Marc Oliver Pleinert have been investigating this question in their research.
