Physicists achieve first-ever 'quadsqueezing' quantum interaction
Researchers at the University of Oxford have demonstrated a new type of quantum interaction using a single trapped ion. By creating and controlling increasingly complex forms of "squeezing" – including a fourth-order effect known as quadsqueezing – the team has, for the first time, made previously unreachable quantum effects experimentally accessible. The approach also provides a new way to engineer these interactions, with potential applications in quantum simulation, sensing, and computing. Their results have been published in Nature Physics:
Băzăvan, O., et al. Squeezing, trisqueezing and quadsqueezing in a hybrid oscillator–spin system, Nature Physics (2026). DOI: 10.1038/s41567-026-03222-6
