Researchers are leveraging quantum mechanical properties to overcome the limits of silicon semiconductor technology. Silicon transistors, which are used to amplify and switch signals, are a critical component in most electronic devices, from smartphones to automobiles. But silicon semiconductor technology is held back by a fundamental physical limit that prevents transistors from operating below a certain voltage.

By emulating a magnetic field on a superconducting quantum computer, researchers can probe complex properties of materials. Quantum computers hold the promise to emulate complex materials, helping researchers better understand the physical properties that arise from interacting atoms and electrons. This may one day lead to the discovery or design of better semiconductors, insulators, or superconductors that could be used to make ever faster, more powerful, and more energy-efficient electronics.

For the first time since the discovery of the material MnBi2Te4 (MBT), researchers at the University of Twente have successfully made it behave like a superconductor. This marks an important step in understanding MBT and is significant for future technologies, such as new methods of information processing and quantum computing.

An international research team has achieved a breakthrough in atomically thin antiferromagnetic tunnel junctions. This shows the great potential of antiferromagnetic materials for storage technology. Spintronics (spin electronics) deals with the use of electron spin in electronic devices. In contrast to conventional electronics, which only uses the charge of the electrons, spintronics also uses the spin of the electrons, i.e. a "direction of rotation" at the atomic level, to store and process information.

Groundbreaking research that used a NASA-equipped plane to fly over thunderclouds has described a new kind of radiation New research into the causes of lightning strikes, which could lead to better understanding and real-time forecasting of thunderstorms in the future, has been released today. Two studies published in Nature conclude that gamma ray generation from thunderstorms may be more common and take more forms than previously thought.

Spin waves with short wavelengths make magnonic computer components possible A new study by the University of Vienna, the Max Planck Institute for Intelligent Systems in Stuttgart and the Helmholtz Centres in Berlin and Dresden represents an important step towards further miniaturizing computer components and making them more energy-efficient.

Thanks to innovations in design, control and production technology, brushless drives for pumps and ventilation systems work more efficiently and quietly.

New Computer Simulations Help Scientists Advance Energy-Efficient Microelectronics " layout="backlink-only" Key Takeaways Researchers have developed FerroX, a new open-source, 3D simulation framework that could advance record-breaking energy efficiency in microelectronics by unveiling the microscopic origins of a physical phenomenon called negative capacitance in ferroelectric thin films.

The newly developed robotic leg is inspired by living creatures and jumps over different terrains much more manoeuvrable and energy-efficiently than previous robots Researchers have developed the first robotic leg that is powered by artificial electro-hydraulic muscles and automatically adapts to uneven terrain.

Physicists from Würzburg present a nanometre-sized light antenna with electrically modulated surface properties - a breakthrough that could pave the way for faster computer chips. Today's computers reach their physical limits when it comes to speed. Semiconductor components usually operate at a maximum usable frequency of a few gigahertz - which corresponds to several billion computing operations per second.

Researchers at ETH Zurich and the Max Planck Institute for Intelligent Systems have developed a robotic leg with artificial muscles. Inspired by living creatures, it jumps across different terrains in an agile and energy-efficient manner. Inventors and researchers have been developing robots for almost 70 years.

Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could also be used in technical applications with electromagnetic waves. Be it water, light or sound: waves usually propagate in the same way forwards as in the backward direction. As a consequence, when we are speaking to someone standing some distance away from us, that person can hear us as well as we can hear them.

Lightwave electronics aim to integrate optical and electronic systems at incredibly high speeds, leveraging the ultrafast oscillations of light fields. Imagine how a phone call works: Your voice is converted into electronic signals, shifted up to higher frequencies, transmitted over long distances, and then shifted back down so it can be heard clearly on the other end.

Superconductivity theory proposed by Würzburg physics team validated in international experiment: Cooper pairs display wave-like distribution in Kagome metals, enabling new technological applications like superconducting diodes. For about fifteen years, Kagome materials with their star-shaped structure reminiscent of a Japanese basketry pattern have captivated global research.

How can diseases of the cardiovascular system be detected before symptoms appear? Researchers at Graz University of Technology (TU Graz) have found a way to track them down at an early stage. Cardiovascular diseases are among the most common causes of death worldwide. They are often only discovered when symptoms have already appeared and the disease is already relatively advanced.

The work, originating from ultrathin materials, could impact future electronics and establishes a new way to study these particles through a powerful instrument at the Brookhaven National Laboratory. MIT physicists and colleagues report new insights into exotic particles key to a form of magnetism that has attracted growing interest because it originates from ultrathin materials only a few atomic layers thick.

Researchers at QuTech developed somersaulting spin qubits for universal quantum logic. This achievement may enable efficient control of large semiconductor qubit arrays. The research group published their demonstration of hopping spins in Nature Communications and their work on somersaulting spins in Science.

A University of Waterloo engineer has paired inexpensive wireless communication antennas with artificial intelligence (AI) to improve how doctors can detect bone fractures. Determining bone fractures using traditional diagnostic methods such as x-rays, computed tomography (CT) scans, and magnetic resonance imaging (MRI) takes time - such equipment is not readily available in ambulances or primary care facilities and, with health care services in high demand, many people have to wait for an x-ray or scan once they arrive at the hospital.

Doctoral students Bart van der Holst and Gijs Verhoeven investigated financial measures for grid operators to make better use of the existing grid capacity. Our electricity grid cannot keep up with the energy transition. New schools, businesses and neighborhoods have to wait for a connection and solar panels are already switched off at peak times.

EPFL engineers have created a device that can efficiently convert heat into electrical voltage at temperatures lower than that of outer space. The innovation could help overcome a significant obstacle to the advancement of quantum computing technologies, which require extremely low temperatures to function optimally.
