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).

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.

IonQ Links Two Remote Quantum Processors with Photonic Interconnect

IonQ announced the first photonic interconnect between two remote commercial trapped-ion quantum computers, linking two IonQ systems at a distance to demonstrate entanglement and networked quantum operations. Conducted with the Air Force Research Laboratory, the milestone validates photon-based links for distributed quantum hardware and advances IonQ’s roadmap toward modular, fault-tolerant systems and a quantum internet, building on their 99.99% two-qubit gate fidelity record.
