Penn-led researchers have shown for the first time that multiple, information-carrying light signals can be safely guided through chip-based, reconfigurable networks using topology, the esoteric branch of mathematics that says donuts and mugs are identical. Because topological properties remain stable even when objects are deformed—hence the field equating mugs and donuts, since both have one […]

Glass appears to be a solid, but in theory it sometimes behaves more like an extremely slow liquid. Physicists in Utrecht now show that glass-like structures can also exist in equilibrium, which is something many theories say should be impossible.

Researchers at the Department of Energy’s SLAC National Accelerator Laboratory and collaborating institutions recently built a generative AI model that can recreate molecular structures from the movement of the molecule’s ions after they are blasted apart by X-rays, a technique called Coulomb explosion imaging.

Quantum communication systems are emerging solutions to transmit information between devices in a network leveraging quantum mechanical phenomena, such as entanglement. Entanglement is a quantum effect that entails a link between two or more particles that share a unified state even at a distance, so that measuring one instantly affects the other.

For the first time, a quantum radiation reaction in strong electromagnetic fields has been demonstrated experimentally by allowing electrons to collide with an extremely intense and powerful laser beam. The research findings provide insights needed for new quantum-mechanical computational models and clues to how the laws of physics operate near neutron stars or black holes. […]

Quantum catalysts are specialized resources that enable quantum state transformations previously thought impossible, holding promise for advancements in quantum computing and thermodynamics. A recent international study has identified the conditions under which these catalysts can operate reliably even amid environmental noise, marking a significant step toward practical quantum technologies.
