A quantum “tornado” is a simplified term for an orbital vortex line, and work led by Maximilian Ünzelmann, a Complexity and Topology in Quantum Matter (ct.qmat) postdoctoral researcher at the Universities of Würzburg and Dresden in Germany, experimentally demonstrated electrons form these vortices within the momentum space of quantum semimetal tantalum arsenide (TaAs). Momentum space describes electron motion in terms of energy and direction—not a precise physical position.

Inspired by the rapid evolution and broad applications of vortex beams, an international team of researchers from China, Japan, and Australia set out to address a few challenges of traditional population inversion lasers—namely limitations in wavelength scalability and power scaling. Drawing upon their earlier work with diamond-based lasers, the researchers realized diamond’s exceptional thermo-optical properties could offer a breakthrough solution.

Entanglement, the virtual link by which information can be exchanged across vast distances, is the cornerstone of modern quantum technologies essential for communication and computing. Unfortunately, quantum entangled states are notoriously fragile and decay when they experience a perturbation. This can be as mundane as background and stray light, noisy detectors, lost photons, or defects within materials, common effects in real-world quantum systems, which render the link useless.
