Scientists Flip the Script and Solve a Longstanding Spintronics Challenge

A breakthrough in spintronics reveals that material defects can be harnessed to boost device efficiency, overturning decades of assumptions. Scientists have discovered a way to transform what was once considered a major problem in electronics, material defects, into a powerful quantum-based advantage. This breakthrough could open the door to a new generation of spintronic devices that operate with extremely low power demands. Spintronics, short for “spin electronics,” is an area of research that seeks to move beyond the boundaries of traditional electronic technology. Standard devices depend solely on the electrical charge of electrons to process and store data. In contrast, spintronics taps into two additional quantum features: spin angular momentum, which can be pictured as an inherent “up” or “down” orientation of each electron, and orbital angular momentum, which describes the paths electrons follow as they circle atomic nuclei. By using these added dimensions, spintronic systems...

Scientists Just Split a Single Photon. Here’s What They Found

Physicists have, for the first time, shown that even a single photon obeys one of nature’s strictest rules: conservation of angular momentum. Achieved only once in a billion attempts, this needle-in-a-haystack success not only proves a cornerstone law of physics at the smallest scale but also opens a pathway to advanced quantum technologies , from entangled states to secure communication. Quantum-Level Confirmation of Angular Momentum Conservation Researchers at Tampere University, working with colleagues in Germany and India, have demonstrated for the first time that angular momentum remains conserved when a single photon splits into two. This result confirms a core principle of physics at the quantum scale and marks a milestone that could help in creating advanced quantum states for use in computing, communication, and sensing technologies. Conservation laws are central to science because they determine which processes are possible and which are not. A familiar example is seen in bi...

Lost Particle Resurfaces As the Key to Universal Quantum Computing

A discarded mathematical oddity has become the key to unlocking universal quantum computing. By combining Ising anyons with a newly recognized particle, the neglecton, researchers showed that complex computations could be done with braiding alone. This breakthrough could make once-impossible quantum operations a reality. Fragile Qubits and the Quantum Challenge Quantum computers could one day tackle problems that even the most advanced supercomputers cannot approach. Yet the machines available today are extremely delicate. Their basic units of information, called quantum bits or “qubits,” are highly sensitive to their surroundings, which causes frequent disruptions and rapidly accumulating errors. A leading strategy for overcoming this weakness is topological quantum computing. Instead of relying on fragile qubits, this method seeks to safeguard quantum information by embedding it within the geometric properties of unusual particles known as anyons. Predicted to exist in certain two-di...

Scientists Create New Magnetic State: The Magneto-Ionic Vortex (“Vortion”)

By controlling this state, researchers can enable the development of smarter, reconfigurable, and energy-efficient devices that function like the brain. Researchers at the Universitat Autònoma de Barcelona (UAB) have successfully created a new form of magnetic state known as a magneto-ionic vortex, or “vortion.” Their findings, published in Nature Communications, demonstrate an unprecedented ability to control magnetic properties at the nanoscale under normal room temperature conditions. This achievement could pave the way for next-generation magnetic technologies . As the growth of Big Data continues, the energy needs of information technologies have risen sharply. In most systems, data is stored using electric currents, but this process generates excess heat and wastes energy. A more efficient approach is to control magnetic memory through voltage rather than current. Magneto-ionic materials make this possible by enabling their magnetic properties to be adjusted when ions are insert...
