Oxford researchers unlock first quadsqueezing in quantum systems with trapped ion
Oxford physicists demonstrated the first-ever quadsqueezing, a fourth-order quantum squeezing, by using two non-commuting forces on a single trapped ion to generate higher-order interactions; alongside standard squeezing and trisqueezing, quadsqueezing was produced more than 100 times faster than conventional methods, enabling new quantum-control capabilities with potential applications in quantum simulation, sensing, and computing, as reported in Nature Physics (May 1, 2026).
