A team of researchers led by the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) developed an approach that enabled them to directly observe how electrons interact with defects in advanced semiconductor devices in unprecedented detail. The team’s methodology included an innovative simulation tool that enabled accurate theoretical interpretations of its experimental observations. […]

A Stanford team has documented the first direct observation of quantum jumps of sound in a mechanical resonator, completing an arc of scientific exploration that started more than 100 years ago.

Quantum computers are no longer theoretical concepts. Today, they are being developed to tackle a range of complex problems, including exploring financial risk, modeling complex molecules and optimizing massive logistics networks. However, until now, there has been no way to benchmark the computational power of different systems on the same scale to see how they […]

Researchers have developed a compact, handheld mid-infrared imaging spectrometer that can produce high-resolution chemical maps of a sample without using stains or labels. With further development, the handheld device might provide a portable and easy-to-use way to map the molecular makeup of tissues and other samples.

Every new generation of phone display, television screen and solar panel is the result of precision optics experiments, which use lasers and other light sources to measure the optical properties of candidate materials. These experiments can take months to run, requiring scientists to meticulously angle and adjust delicate light sources, mirrors, cameras and other components […]

In March 2026, scientists succeeded in transporting antiprotons by road for the first time in a purpose-built trap loaded on a truck. The BASE collaboration, which realized this experiment at the European Organization for Nuclear Research (CERN) in Geneva under the lead of Professor Dr Stefan Ulmer and Dr Christian Smorra from Heinrich Heine University […]

Rydberg atoms are considered promising building blocks for quantum computers and their precursors, quantum simulators. Researchers at the 5th Institute of Physics of the University of Stuttgart have achieved record values for the lifetime, size, and storage time of circular Rydberg atoms, a special form of Rydberg atom in which electrons move in a stable […]
