Electrons have an intrinsic angular momentum, the so-called spin, which means that they can align themselves along a magnetic field, much like a compass needle. In addition to the electric charge of electrons, which determines their behaviour in electronic circuits, their spin is increasingly used for storing and processing data. Already now, one can buy MRAM memory elements (magnetic random access memories), in which information is stored in very small but still classical magnets – that is, containing very many…
Interaction with autonomous driving. Optimizing communication between vehicle and driver as a function of the degree of automation is the objective of a research project conducted by Fraunhofer in collaboration with other companies. The researchers are combining sensors for monitoring the vehicle interior with language models to form what are known as vision language models. They are designed to increase the convenience and safety of cars in the future. “Warning, if you keep reading now, you may become nauseous on…
Reducing semiconductor laser production costs by 1/6 with quantum dot lasers for optical communications. Using 6-inch substrates instead of 2-inch: time reduction and mass production achieved. South Korean researchers have successfully developed technology to mass-produce quantum dot lasers, widely used in data centers and quantum communications. This breakthrough paves the way for reducing the production cost of semiconductor lasers to one-sixth of the current cost. Metal-Organic Chemical Vapor Deposition (MOCVD).

Aston Institute of Photonic Research academics are part of a team that sent data at a rate of 402 terabits per second This beats their previous record of 301 terabits per second They constructed the first optical transmission system covering six wavelength bands. Aston University researchers are part of a team that has sent data at a record rate of 402 terabits per second using commercially available optical fibre. This beats their previous record, announced in March 2024, of 301…
Study shows Manipulation Possibilities. On behalf of the German Federal Office for Information Security (BSI), experts from the IHP – Leibniz Institute for High Performance Microelectronics prepared the study “Analysis of Hardware Manipulations in Distributed Manufacturing Processes (PANDA)”. The result: Safety properties or functionality can be negatively affected in all sub-steps. IHP scientist Hon. Prof. Zoya Dyka shows the BSI employees where the mainboard of a laptop could be manipulated.(c) Franziska Wegner / IHP Hardware Trojans could become a threat….
In a single leap from tabletop to the microscale, engineers at Stanford have produced the world’s first practical titanium-sapphire laser on a chip, democratizing a once-exclusive technology. As lasers go, those made of Titanium-sapphire (Ti:sapphire) are considered to have “unmatched” performance. They are indispensable in many fields, including cutting-edge quantum optics, spectroscopy, and neuroscience. But that performance comes at a steep price. Ti:sapphire lasers are big, on the order of cubic feet in volume. They are expensive, costing hundreds of…
New FAMU-FSU research shows importance of precise topography in solid neon qubits. Quantum computers have the potential to be revolutionary tools for their ability to perform calculations that would take classical computers many years to resolve. But to make an effective quantum computer, you need a reliable quantum bit, or qubit, that can exist in a simultaneous 0 or 1 state for a sufficiently long period, known as its coherence time. One promising approach is trapping a single electron on…
Compression standard for haptics published. With the help of the new HCTI standard, sensations can be transmitted over the Internet. The tactile counterpart to JPEG, MP3 and MPEG was developed by a consortium led by the Technical University of Munich (TUM). HCTI can be used in tele-surgery, tele-driving or in the gaming industry. What JPEG, MP3 and MPEG are for images, audio and video, haptic codecs are for transmitting the sense of touch via the Internet. After eight years of…
North Carolina State University researchers have developed a kirigami-inspired mechanical computer that uses a complex structure of rigid, interconnected polymer cubes to store, retrieve and erase data without relying on electronic components. The system also includes a reversible feature that allows users to control when data editing is permitted and when data should be locked in place. Mechanical computers are computers that operate using mechanical components rather than electronic ones. Historically, these mechanical components have been things like levers or…
DFKI unveils pioneering approach to safe and verifiable humanoid walking. Recent advances in robotics based on data-driven AI hold promise for a wide range of practical applications. However, ensuring the safety of these applications is a challenge. The German Research Center for Artificial Intelligence (DFKI) in Bremen has developed innovative control methods for complex systems, combining the advantages of fast self-learning and reliable verification via symbolic models. With this hybrid AI approach, the project funded by the Federal Ministry of…

CARMEN teaches strategies to help improve memory and executive function. Meet CARMEN, short for Cognitively Assistive Robot for Motivation and Neurorehabilitation–a small, tabletop robot designed to help people with mild cognitive impairment (MCI) learn skills to improve memory, attention, and executive functioning at home. Unlike other robots in this space, CARMEN was developed by the research team at the University of California San Diego in collaboration with clinicians, people with MCI, and their care partners. To the best of the…
The potential of quantum computers is currently thwarted by a trade-off problem. Quantum systems that can carry out complex operations are less tolerant to errors and noise, while systems that are more protected against noise are harder and slower to compute with. Now a research team from Chalmers University of Technology, in Sweden, has created a unique system that combats the dilemma, thus paving the way for longer computation time and more robust quantum computers. For the impact of quantum computers…
…including objects blocked from view. This technique could lead to safer autonomous vehicles, more efficient AR/VR headsets, or faster warehouse robots. Imagine driving through a tunnel in an autonomous vehicle, but unbeknownst to you, a crash has stopped traffic up ahead. Normally, you’d need to rely on the car in front of you to know you should start braking. But what if your vehicle could see around the car ahead and apply the brakes even sooner? Researchers from MIT and…
