Summary

Story summary

University of Oxford physicists created a quadsqueezing state with a trapped ion.
Dr. Oana Bazavan used laser steering to generate the state 100 times faster than prior methods.
Two non-commuting laser forces with the ion’s spin prevented signal loss typical of interactions.
Reconstructed Wigner functions displayed second-, third-, and fourth-order patterns that matched simulations.
Dr. Raghavendra Srinivas said scaling to multiple ions must retain the speed advantage for quantum technologies.
