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.

Researchers found a Wordle strategy that wins 99% of the time

Researchers developed a Wordle-solving strategy that succeeds 99% of the time by focusing on information gain rather than likely answers. The method uses Shannon entropy to identify guesses that reveal the most about the hidden word. Each guess is designed to slash uncertainty and narrow the possibilities faster. The result significantly outperformed more traditional Wordle […] more…

SpaceX wants to build AI data centers in space. Will it work?

The race to build data centers in space is gaining momentum as AI drives unprecedented demand for computing power. Orbital facilities could tap into abundant solar energy and avoid many of the environmental challenges faced on Earth. Yet space remains a harsh and expensive place to operate, with major hurdles including cooling, maintenance, radiation exposure, […] more…

Superconductivity breakthrough could unlock ultra-efficient electronics

A clever nanoscale redesign may have solved one of superconductivity’s biggest problems. Researchers in Sweden discovered that by subtly sculpting the surface beneath an ultrathin superconducting material, they could make it stay superconducting at higher temperatures and under much stronger magnetic fields. more…

One-way quantum synchronization could make quantum computers more reliable

Scientists at RIKEN have proposed a new way to make quantum systems synchronize in only one direction—like a one-way street for sound particles known as phonons. The breakthrough combines two quantum effects to create a form of one-way quantum synchronization that remains surprisingly stable even when exposed to manufacturing flaws and environmental noise, two major […] more…

AI-designed universal coronavirus vaccine passes first human trial

Scientists have successfully tested an AI-designed universal coronavirus vaccine in humans for the first time, finding it to be safe and well tolerated. The vaccine generated immune responses against multiple coronaviruses, including SARS-CoV-2, SARS, and related bat viruses with pandemic potential. By targeting features shared across an entire virus family, it aims to provide protection […] more…

Scientists discover a hidden quantum world inside cobalt

Scientists have uncovered unexpected quantum complexity inside cobalt, a metal long thought to be fully understood. Advanced measurements revealed a dense network of topological electronic states that remain robust at room temperature. These states enable extremely fast electron behavior and can be switched or controlled using magnetism. The discovery could open new paths toward next-generation […] more…
