New Cryogenic Vacuum Chamber Cuts Noise for Quantum Ion Trapping

Georgia Tech Research Institute unveiled a cryogenic vacuum chamber that dramatically reduces vibration and magnetic‑field noise for trapped‑ion quantum experiments. The design embeds magnetic shielding inside the chamber and uses ceramic‑plastic posts for vibration isolation, while an integrated RF coil enables dynamical decoupling. Early tests show ion coherence times rising from 24 ms to 810 ms and state‑detection fidelity reaching 99.9963 % in just 50 µs. The results, published in Applied Physics Letters and developed with Los Alamos National Laboratory, promise faster, more reliable quantum‑computing operations.
