Credit: Laurentiu Robu, pexels.com More The ability to securely transmit information over the internet is extremely important, but most of the time, eavesdroppers can still generally determine who the sender and receiver are. In some highly confidential situations, it is important that the sender’s and receiver’s identities remain anonymous. Over the past couple of decades,

Using the link layer protocol, higher-layer software can request the creation of entanglement without needing to know which quantum hardware system is in the box. Credit: QuTech/Scixel More Researchers from QuTech have achieved a world’s first in quantum internet technology. A team led by Professor Stephanie Wehner has developed a so-called link layer protocol that

The Kohnen Station is a container settlement in the Antarctic, from whose vicinity the snow samples in which iron-60 was found originate. Credit: Martin Leonhardt/Alfred-Wegener-Institut (AWI) More A team of scientists hauled 500 kilograms of fresh snow back from Antarctica, melted it, and sifted through the particles that remained. Their analysis yielded a surprise: The

Theoretical prediction of the image of the black hole from the table-top experiment. The radius of the ring depends on the temperature. The image of the black hole is deformed as the observation point θobs is varied.

Three-dimensional band topology is experimentally mapped out showing nodal lines in good agreement with theoretical prediction. Credit: HKUST More Physicists from the Hong Kong University of Science and Technology (HKUST) and Peking University (PKU) have successfully created the world’s first 3-D simulation of topological matter consisting of ultracold atoms. Previous attempts at topological matter simulations

This cutaway view shows stripes of higher and lower electron density — ‘charge stripes’ — within a copper-based superconducting material. Experiments with SLAC’s X-ray laser directly observed how those stripes fluctuate when hit with a pulse of light, a step toward understanding how they interact with high-temperature superconductivity.

Doped charges in the CuO2 planes of cuprate superconductors form regular one-dimensional ‘stripes’ at low temperatures. Excitation with ultrafast near-infrared pulses allows direct observation of diffusive charge dynamics, which may be involved in the establishing in-plane superconductivity.

This image shows the transition between Cooper pair density (indicated by blue dots) and charge density waves. Argonne scientists found that by introducing defects, they could disrupt charge density waves and increase superconductivity.

Particles emerging from proton collisions at CERN’s Large Hadron Collider travel through through this stories-high, many-layered instrument, the CMS detector. In 2026, the LHC will produce 20 times the data it does currently, and CMS is currently undergoing upgrades to read and process the data deluge.
