Oxford team creates tunable trapped-ion quantum superpositions.

Summary

Story summary

Oxford physicists created new quantum superposition states with a trapped ion.
They engineered spin-motion entanglement, performed a mid-circuit measurement that collapsed the ion’s motion, and tuned parameters to shape component size, orientation and separation, producing exotic states whose interference patterns and Wigner negativity confirmed genuine nonclassical superpositions.
Led by Dr. Sebastian Saner, the team expects the method to aid quantum computing, error-correction, sensing and research on the quantum-classical boundary.
