Oxford researchers push quantum limits with 100x faster quadsqueezing
Oxford researchers demonstrate quadsqueezing, a rare fourth‑order quantum interaction, by applying non‑commutativity to a single trapped ion, achieving the effect 100× faster than expected. The approach reshapes quantum harmonic oscillators and overcomes prior speed limits, opening new possibilities for ultra‑sensitive sensors and advanced quantum computing, with the findings published in Nature Physics by Dr. Oana Băzăvan and colleagues.
