The research team, led by physics professor Nuh Gedik, concentrated on a material called FePS₃, a type of antiferromagnet that transitions to a non-magnetic state at around −247°F. They hypothesized that precisely exciting the vibrations of FePS₃’s atoms with lasers could disrupt its typical antiferromagnetic alignment and induce a new magnetic state.

In conventional magnets (ferromagnets), all atomic spins align in the same direction, making their magnetic field easy to control. In contrast, antiferromagnets have a more complex up-down-up-down spin pattern that cancels out, resulting in zero net magnetization. While this property makes antiferromagnets highly resistant to stray magnetic influences – an advantage for secure data storage – it also creates challenges in intentionally switching them between “0” and “1” states for computing.

Gedik’s innovative laser-driven approach seeks to overcome this obstacle, potentially unlocking antiferromagnets for future high-performance memory and computational technologies.

Asus is only teasing its new Zenbook at this time, so we’ll have to wait until its formal introduction at the Always Incredible launch event on January 7 to get the full scoop. Given the battery life claims, however, it is likely that this new Copilot+ PC will be powered by a Snapdragon X chip.

The manic pace of sharing, storing, securing, and serving data has a manic price—power consumption. To counter this, Virginia Tech mathematicians are leveraging algebraic geometry to target the inefficiencies of data centers.

“We as individuals generate tons of data all the time, not to mention what large companies are producing,” said Gretchen Matthews, mathematics professor and director of the Southwest Virginia node of the Commonwealth Cyber Initiative. “Backing up that data can mean replicating and storing twice or three times as much information if we don’t consider smart alternatives.”

Instead of energy-intensive data replication, Matthews and Hiram Lopez, assistant professor of mathematics, explored using certain algebraic structures to break the information into pieces and spread it out among servers in close proximity to each other. When one server goes down, the algorithm can poll the neighboring servers until it recovers the .

At the Berlin synchrotron radiation source BESSY II, the largest magnetic anisotropy of a single molecule ever measured experimentally has been determined. The larger a molecule’s anisotropy is, the better suited it is as a molecular nanomagnet. Such nanomagnets have a wide range of potential applications, for example, in energy-efficient data storage.

Researchers from the Max Planck Institute for Kohlenforschung (MPI KOFO), the Joint Lab EPR4Energy of the Max Planck Institute for Chemical Energy Conversion (MPI CEC) and the Helmholtz-Zentrum Berlin were involved in the study.

The research involved a bismuth complex synthesized in the group of Josep Cornella (MPI KOFO). This molecule has unique magnetic properties that a team led by Frank Neese (MPI KOFO) recently predicted in . So far, however, all attempts to measure the magnetic properties of the bismuth complex and thus experimentally confirm the theoretical predictions have failed.

Linköping University’s experiment confirms a key theoretical link between quantum mechanics and information theory, highlighting future implications for quantum technology and secure communication.

Researchers at Linköping University and their collaborators have successfully confirmed a decade-old theory linking the complementarity principle—a fundamental concept in quantum mechanics—with information theory. Their study, published in the journal Science Advances, provides valuable insights for understanding future quantum communication, metrology, and cryptography.

“Our results have no clear or direct application right now. It’s basic research that lays the foundation for future technologies in quantum information and quantum computers. There’s enormous potential for completely new discoveries in many different research fields,” says Guilherme B Xavier, researcher in quantum communication at Linköping University, Sweden.

Engineers at Northwestern University have demonstrated quantum teleportation over a fiber optic cable already carrying Internet traffic. This feat, published in the journal Optica, opens up new possibilities for combining quantum communication with existing Internet infrastructure. It also has major implications for the field of advanced sensing technologies and quantum computing applications.

Quantum teleportation, a process that harnesses the power of quantum entanglement, enables an ultra-fast and secure method of information sharing between distant network users. Unlike traditional communication methods, quantum teleportation does not require the physical transmission of particles. Instead, it relies on entangled particles exchanging information over great distances.

Nobody thought it would be possible to achieve this, according to Professor Prem Kumar, who led the study. “Our work shows a path towards next-generation quantum and classical networks sharing a unified fiber optic infrastructure. Basically, it opens the door to pushing quantum communications to the next level.”

The speed of the human brain’s ability to process information has been investigated in a new study, and according to scientists, we’re not as mentally quick as we might like to think.

In fact, research suggests our brains process information at a speed of just 10 bits per second. But how is this possible, in comparison to the trillions of operations computers can perform every second?

Research suggests this is the result of how we internally process thoughts in single file, making for a slow, congested queue.
