In today’s world, the fight against counterfeiting is more critical than ever. Counterfeiting affects about 3% of global trade, posing significant risks to the economy and public safety. From fake pharmaceuticals to counterfeit currency, the need for secure and reliable authentication methods is paramount. Authentication labels are commonly used—such as holograms on bank notes and […]

Scientists at the University of Würzburg and the German national metrology institute (PTB) have carried out an experiment that realizes a new kind of quantum standard of resistance. It’s based on the Quantum Anomalous Hall Effect.

The quarks that make up the nuclei of all atoms around us are known to “mix”: the different types of quark occasionally change into one another. The amounts in which these processes happen are not very well known, though—and the theoretical values don’t even add up to 100%. UvA-IoP physicist Jordy de Vries and colleagues […]

Imagine placing an object under a microscope and pressing a button to rearrange the surface atoms with atomic-scale precision. This once sci-fi scenario is now a reality thanks to pioneering research published in Applied Surface Science.

Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and collaborators have a new way to use data from high-energy particle smashups to peer inside protons. Their approach uses quantum information science to map out how particle tracks streaming from electron-proton collisions are influenced by quantum entanglement inside the proton.
