Quantum Higgs boson- type echo discovered in niobium-based superconductors used in quantum computing circuits

https://www.ameslab.gov/news/new-quantum-echo-discovered-in-superconductors

"echo appears during superconducting phase transition... collective vibrations exist for very short time/ have complex interactions with quasiparticles, electron-like excitations emerging from superconductivity breakdown, signals enabling remembering/ revealing of hidden quantum pathways within material... THz pulsed echoesencode stores/ retrieves quantum information embedded within superconducting material... quantum coherence observation/ control for quantum information storage/ processing"
