What kills Schrödinger’s cat? Underground experiment rules out gravity model for quantum decoherence

Somewhere between the microscopic realm of elementary particles and the macroscopic world of human beings, something strange happens: The rules of quantum physics, which work so exquisitely for tiny atoms, seem to lose their grip as objects grow larger. Pondering where and how this shift from small-scale quantum fuzziness to everyday sharp certainty happens gives […]

New benchmark puts quantum computers to the test and reveals their limitations

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 […]

Diamond quantum sensors can detect heart magnetism at room temperature without skin contact

Physicists at Johannes Gutenberg University Mainz (JGU) have developed a technology that uses quantum sensors to measure biomagnetic signals, such as heart activity. Researchers from the DIAQNOS (DIAmond-based Quantum Sensing for NeurOSurgery) flagship project, coordinated by Dr. Arne Wickenbrock in Mainz, have demonstrated the potential of quantum technology for future medical applications.

Handheld scanner delivers lab-quality chemical composition maps using infrared light

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.

Is dark matter ‘natural?’ Physicist puts the question to the test

Dark matter is one of the oldest open problems in physics. It makes up most of the matter in the universe and shapes how galaxies form and move, yet no one has ever directly detected it. Physicists have proposed dozens of candidates to explain it: exotic new particles, black holes formed moments after the Big […]

Robotic lab sets up and runs optics experiments on demand

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 […]

Hot electrons reveal electronic collisions may raise resistance in twisted graphene

When a material heats up, its electrical resistance often rises. The harder question is what, exactly, is getting in the way. The electrons carrying the current may be scattered by vibrations of the material’s atomic lattice, known as phonons. They may also collide with one another. Frustratingly, a conventional temperature test warms the electrons and […]

Mobile trap transports 92 antiprotons by road and stores them for over a month in world first

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 […]

Roll waves emerge as uniform water flow destabilizes on steep slopes, equations show

When it rains, traveling waves appear on steep asphalt pavement, slowly making their way down the slope. Because these so-called “roll waves” propagate without deforming and are typically characterized by abrupt discontinuities, they play an important role in hydraulic engineering. Understanding unsteady flows like roll waves is crucial for the design, management and safety of […]

Circular Rydberg atoms set three records, staying stable for 11 milliseconds

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 […]
