Kyoto, Japan -- The concept of quantum entanglement is emblematic of the gap between classical and quantum physics. Referring to a situation in which it is impossible to describe the physics of each photon separately, this key characteristic of quantum mechanics defies the classical expectation that each particle should have a reality of its own, which gravely concerned Einstein. Understanding the potential of this concept is essential for the realization of powerful new quantum technologies.

Developing such technologies will require the ability to freely generate a multi-photon quantum entangled state, and then to efficiently identify what kind of entangled state is present. However, when performing conventional quantum tomography, a method commonly used for state estimation, the number of measurements required grows exponentially with the number of photons, posing a significant data collection problem.

If available, an entangled measurement can identify the entangled state with a one-shot approach. Such a measurement for the Greenberger-Horne-Zeilinger -- GHZ -- entangled quantum state has been realized, but for the W state, the other representative entangled multi-photon state, it has been neither proposed nor discovered experimentally.

Complex biological systems are more than the sum of their parts – their properties emerge from the dynamic interaction of their components, such as molecules or cells. PhD researchers now have the opportunity to develop their own theoretical perspective on these systems as part of an international Doctoral Network. A European consortium initiated by researchers from the University of Göttingen, the Max Planck Institute for Dynamics and Self-Organization (MPI-DS), and the University of Edinburgh has been awarded €4.5M by Marie Skłodowska-Curie Actions to coordinate the network. The network consists of twelve European universities and research centres along with a number of partners outside academia. It is coordinated by the University of Edinburgh.

Wiley announces the release of KnowItAll 2026, featuring the new Trendfinder application that integrates chemometric analysis directly into the interface to uncover meaningful patterns in complex spectral and chromatographic datasets.

What happens when you hurl molecules faster than sound through a vacuum chamber nearly as cold as space itself? At the University of Missouri, researchers are finding out — and discovering new ways to detect molecules under extreme conditions.

Researchers report an in-situ passivation strategy for pure-blue perovskite light-emitting diodes (PeLEDs), promising for next-generation displays, fabricated by vacuum thermal evaporation. Co-evaporating a phenanthroline ligand (BUPH1) with perovskite precursors coordinates Pb(II) and suppresses halide-vacancy defects, reducing non-radiative losses and spectral drift. Devices emit at 472 nm (FWHM 19 nm) with an EQE of 3.1%—among the highest for thermally evaporated pure-blue PeLEDs—and maintain color stability, compatible with the ITU-R Rec.2020 wide-gamut standard. Next steps target luminance and longer lifetime via additional passivation strategies, toward thermally evaporated device stacks for industrial manufacturing.

Earthquake-induced liquefaction of loose, sandy soil can be extensively damaging for built environment. In recent times, chemical grouting of the sand is being used as a method to enhance soil stability and reduce the risk of liquefaction. However, a standardized and effective method to test the resistance is necessary in order to refine the method. In this study, scientists explored the potential of stress-controlled and strain-controlled cyclic triaxial testing.

Biologists have long known that amino acids can help stabilize proteins, for example as additives to pharmaceutical formulations. In trying to understand why this works, EPFL and MIT researchers have discovered a fundamental stabilizing effect of all small molecules, creating exciting possibilities for controlling particles in solution.
