Trapped ions are at the forefront of quantum computing, simulation, and precision metrology. Through a partnership between Duke University, University of Maryland Rice University, and Translume Inc., we have developed and characterized 3D monolithic, segmented blade traps. Our approach merges the advantages of macroscopic traps—including high-depth symmetric potentials and superior optical access—with the scalability and geometric accuracy of microfabrication.

Our third-generation architecture, currently operating at Rice, focuses on minimizing heating rates and micromotion instability by isolating DC electrodes from high-voltage RF and enhancing heat dissipation. The latest fourth-generation trap, deployed at UMD, optimizes the ion-electrode gap to improve stability and lower the voltage requirements for target secular frequencies.

Pizza and drinks will be served after the seminar in ATL 2117.
