Josephson junctions can operate with a single superconductor, experiment confirms

Dec 29, 2025 Experiments show Josephson junction-like behavior can arise with only one superconductor, challenging the standard two-superconductor model. (Nanowerk News) Separate two superconductors with a thin layer of material and something strange happens. Their superconductivity — a property driven by paired electrons that allows electricity to flow without energy...

Scalable thin-film cavities boost sensitivity of nanodiamond quantum sensors nearly fivefold

Dec 29, 2025 Polymer thin-film optical cavities boost the magnetic sensing sensitivity of nanodiamond quantum sensors nearly fivefold while enabling centimeter-scale fabrication with standard manufacturing techniques. (Nanowerk Spotlight) Somewhere inside many diamonds lies a flaw. Not the inclusions that diminish a gemstone's value, but something far stranger: individual atoms out...
