Scientists just overturned a century-old physics assumption

Scientists at Carnegie Mellon University have discovered an unexpected form of the Hall effect, overturning the long-held assumption that this electrical response only appears when a magnetic field points perpendicular to a material. Beyond expanding a century-old principle of physics, the finding could eventually lead to simpler magnetic sensors for electronics, transportation, and medical technologies. more…

A “quantum bath” puts quantum entanglement on autopilot

Physicists have demonstrated a new way to entangle distant quantum bits without the constant measurements and active control normally required. The team created a “quantum bath,” a shared environment filled with correlated microwave photons that automatically pushes separated qubits into an entangled state and helps keep them there. The experiment confirms a theoretical prediction made […] more…

IBM quantum computer solves classically intractable problem in 15 minutes

IBM and University of Chicago researchers have completed a quantum computation that leading classical methods could not practically reproduce. The system used 70 error-corrected logical qubits and finished the task in roughly 15 minutes while also providing statistical evidence that the result was reliable. more…

Scientists switch on a strange new form of magnetism in an ultrathin material

Scientists have found a surprising way to potentially switch on an unusual form of magnetism in ruthenium dioxide, a material that normally appears nonmagnetic. When the material was made into an ultrathin film only a few atomic layers thick and placed under strain, its electrons developed patterns consistent with altermagnetism, a recently proposed magnetic state […] more…

A tiny “rainbow on a chip” could help supercharge 6G networks

Researchers have created a tiny chip that produces a stable “rainbow” of light capable of generating multiple high-frequency signals at once, potentially boosting the speed and capacity of future 6G networks.

Scientists catch a hidden electronic state forming in just 30 femtoseconds

Scientists watched a light-triggered hidden state form inside a material in only 30 femtoseconds, revealing a step that had never been seen before. The material first entered a fleeting electronic state in which its bonds reorganized in a repeating pattern, followed by tiny atomic shifts. This ultrafast pathway could offer a new way to control […] more…

Scientists turn DNA into a memory device that uses 100x less power

Researchers combined synthetic DNA with a semiconductor to create an ultra-low-power memory device capable of storing and processing information in the same place. The bio-hybrid technology could eventually help make AI systems and next-generation computers far more energy efficient. more…

World’s first superconducting quantum heat engine could help unlock massive quantum computers

A tiny superconducting engine has successfully converted heat near absolute zero into useful work, demonstrating the first cyclic quantum heat engine of its kind. Future versions could operate autonomously inside quantum computers, potentially eliminating huge numbers of costly, noise-producing microwave cables. more…

Sunlight creates quantum entanglement once thought to require lasers

Scientists have generated quantum entanglement directly from sunlight, potentially offering a lower-energy alternative to the lasers normally used in quantum technology. Their outdoor experiment produced entangled photons with about 94% similarity to an ideal state. The result could pave the way for simpler quantum satellites, secure communications, and more energy-efficient quantum computing. more…

An ordinary laptop solved a problem thought to require a quantum computer

A quantum problem once described as impossible for classical computers has now been solved using relatively modest hardware. Researchers used tensor networks to compress the overwhelming wave function created by hundreds of entangled qubits, allowing some calculations to run on a laptop. Their results matched both theoretical predictions and simulations performed with a quantum computer. […] more…

Quantum breakthrough links light and magnetism in atomically thin materials

A new review highlights exciting progress in atomically thin quantum materials where light and magnetism work together in ways never before possible. In these materials, light-generated excitons can interact directly with magnetic behavior, creating opportunities to control magnetic states using light alone. Scientists believe this could pave the way for advanced optical memory, quantum devices, […] more…

Physicists say quantum mechanics may not need imaginary numbers after all

Physicists from Heinrich Heine University Düsseldorf (HHU) have examined a fundamental property of quantum mechanics in collaboration with the German Aerospace Center (DLR). In the scientific journal Physical Review Letters, they show that this theory does not necessarily need to be formulated with imaginary numbers – real numbers can in fact also be used. The […] more…

Physicists finally build a quantum material predicted more than a decade ago

Researchers have achieved a major milestone by creating a long-sought two-dimensional quantum material and confirming its unusual conducting edge states. The ability to control these states through strain could make the material a promising platform for future room-temperature quantum electronics. more…

Scientists have combined machine learning with quantum physics to discover two new superconductors and create a much faster way to search for many more. The technique could bring researchers significantly closer to the long-sought goal of a room-temperature superconductor. more…

Tiny magnetic waves could unlock quantum computers the size of a penny

A major breakthrough in quantum technology has turned magnons, tiny magnetic waves once considered too short-lived for practical use, into promising carriers of quantum information. Researchers extended their lifetime by nearly 100 times, reaching up to 18 microseconds, and discovered that the main limitation is not a law of physics but the purity of the […] more…
