Physicists solve 90-year-old puzzle of quantum damped harmonic oscillators
University of Vermont professor Dennis Clougherty (right) and his student Nam Dinh wondered if there are systems in the atomic scale that behave like the vibrating motion of a guitar…
A quantum gas that refuses to heat—physicists observe many-body dynamical localization
Despite being continually kicked and strongly interacting, the atoms no longer absorb energy. The system localizes in momentum space, the momentum distribution literally freezes, a remarkable phenomenon termed many-body dynamical…
Using sound to remember quantum information 30 times longer
A scanning electron microscope image highlighting a single mechanical oscillator, “tuning fork,” from the new work. The false-colored golden lines in the image indicate the location of electrodes that transfer…
The first experimental realization of quantum optical skyrmions in a semiconductor QED system
Polarization profiles of the cavity-enhanced single-photon skyrmions. Credit: Nature Physics (2025). DOI: 10.1038/s41567-025-02973-y “These modes are carefully engineered superpositions of Laguerre-Gaussian states that carry orbital angular momentum, which is essential…
Next-level pixel-particle analogy uses quantum-inspired math to clarify noisy medical images
A medical image denoising method based on principles of quantum mechanics outperform machine learning, statistical methods, and neural networks. The same approach could aid quantum computing performance at scale. Credit:…
Quantum dot technique improves multi-photon state generation
The new approach uses a purely optical technique called stimulated two-photon excitation to generate streams of photons in different polarization states directly from a quantum dot without requiring any active…
