Rice researchers build 3D monolithic ion trap for quantum simulation

Researchers at Rice University have developed a three-dimensional monolithic ion trap made of fused silica that works with heavy ytterbium ions. After three design iterations fixed overheating and ion micromotion, measurements matched simulations; the study appears in Physical Review Applied.

• Fused-silica trap with gold electrodes supports heavy ytterbium ions
• Early prototypes overheated and visibly glowed under radio-frequency voltage
• Third version cut ion heating via plasma-based surface treatment
• Measurements matched prior simulations, confirming device performance
