The approach can detect anomalies in data recorded over time, without the need for any training. Identifying one faulty turbine in a wind farm, which can involve looking at hundreds of signals and millions of data points, is akin to finding a needle in a haystack. Engineers often streamline this complex problem using deep-learning models that can detect anomalies in measurements taken repeatedly over time by each turbine, known as time-series data. But with hundreds of wind turbines recording dozens…
In recent years, urban waterlogging disasters have become more frequent due to rapid urbanization and climate change, severely threatening city infrastructure. Subway tunnels, with their semi-enclosed structure, face significant risks during floods, leading to difficult evacuations and substantial casualties. Statistics show that over 160 cities in China experience flood disasters annually, causing severe economic losses and fatalities. Due to these challenges, in-depth research on flood monitoring and early warning systems for subway tunnels is essential to enhance urban disaster prevention…
Light is an excellent carrier of information used not only for classical communication technologies but also increasingly for quantum applications such as quantum networking and computing. However, processing light signals is far more complex, compared to working with common electronic signals. An international team of researchers including Dr. Olga Kocharovskaya, a distinguished professor in the Department of Physics and Astronomy at Texas A&M University, has demonstrated a novel way of storing and releasing X-ray pulses at the single photon level — a concept…

The Chiplet Center of Excellence commences operations. Three Fraunhofer Institutes have launched a forward-looking research initiative in Dresden: the Chiplet Center of Excellence (CCoE). Its purpose is to partner with industry to drive forward the introduction of chiplet technology. Researchers at the CCoE are working on several fronts for the automotive industry, developing the first workflows and methods for electronics design, demonstrator construction, and the evaluation of reliability. “Chiplets will play a critical role in the global semiconductor industry in…
Researchers at Leibniz University Hannover send entangled photons and laser pulses of the same color over a single optical fiber for the first time. Four researchers from the Institute of Photonics at Leibniz University Hannover have developed a new transmitter-receiver concept for transmitting entangled photons over an optical fiber. This breakthrough could enable the next generation of telecommunications technology, the quantum Internet, to be routed via optical fibers. The quantum Internet promises eavesdropping-proof encryption methods that even future quantum computers…
Two new early career research groups bolster Stuttgart’s quantum photonics research. The first Junior Research Groups for Quantum Photonics have started work at the Carl-Zeiss-Stiftung Center for Quantum Photonics (CZS Center QPhoton), where three universities have been conducting joint research into new quantum technologies since 2022. They are headed by physicist Dr. Laëtitia Farinacci and physicist Dr. Stephan Welte respectively and are based at the University of Stuttgart. Stuttgart’s strong quantum research offers both groups ideal conditions. Dr. Laëtitia Farinacci…
The newly founded Robotics Institute Germany (RIG) has officially begun its operations with an exciting kickoff event. Led by the Technical University of Munich (TUM) and the Karlsruhe Institute of Technology (KIT), the consortium unites research, resources and infrastructures and aims to make Germany the world’s leading location for AI-based robotics. The University of Stuttgart is a founding partner and participates in the RIG with the Institutes for Artificial Intelligence and for Control Engineering of Machine Tools and Manufacturing Units…
Specific physical human-robot interactions are increasingly required in the manufacturing industry, the professional service sector, and healthcare. This necessitates improvements in comfort and convenience as well as in communication between humans and machines. Robots need to be able to predict human actions and recognize intentions. And that calls for flexible metamaterials, and more specifically, flat metasurface antennas with highly integrated electronics that allow for sensing of the near environment. The Fraunhofer FHR has teamed up with six partners in the…
Two-dimensional nano-semiconductors advancing quantum technology. Quantum technology is quantifiable in qubits, which are the most basic unit of data in quantum computers. The operation of qubits is affected by the quantum coherence time required to maintain a quantum wave state. Scientists have hypothesized that moiré excitons — electron-hole pairs confined in moiré interference fringes which overlap with slightly offset patterns — may function as qubits in next-generation nano-semiconductors. However, due to diffraction limits, it has not been possible to focus…
Finding and fixing errors in programme code still takes up a lot of developers’ time. A team at Graz University of Technology has now developed a solution that tackles the biggest time wasters. Modern software applications usually consist of numerous files and several million lines of code. Due to the sheer quantity, finding and correcting faults, known as debugging, is difficult. In many software companies, developers still search for faults manually – something which takes up a large proportion of…
CISPA researcher Adrian Dabrowski, together with colleagues from SBA Research and the University of Vienna, has discovered two major security vulnerabilities in the mobile protocol Voice over WiFi (VoWiFi), also known as WLAN calling. These vulnerabilities put the communication security of millions of mobile phone customers worldwide at risk. Updates to fix the problems have now been implemented. Modern smartphones can establish phone connections not only via mobile networks, but also via Wi-Fi, thus ensuring connectivity even in places with…
Devices could run on ocean bacteria and revolutionize aquatic robotics. Researchers at Binghamton University, State University of New York have developed a self-powered “bug” that can skim across the water, and they hope it will revolutionize aquatic robotics. Futurists predict that more than one trillion autonomous nodes will be integrated into all human activities by 2035 as part of the “internet of things.” Soon, pretty much any object — big or small — will feed information to a central database…
This groundbreaking research demonstrates a potential for quantum networks based on cold-atom integrated nanophotonic circuits. Researchers at Purdue University have trapped alkali atoms (cesium) on an integrated photonic circuit, which behaves like a transistor for photons (the smallest energy unit of light) similar to electronic transistors. These trapped atoms demonstrate the potential to build a quantum network based on cold-atom integrated nanophotonic circuits. The team, led by Chen-Lung Hung, associate professor of physics and astronomy at the Purdue University College…
