Ion Storage Group

The Ion Storage Group conducts experiments on laser cooled atomic ions that are confined in electromagnetic traps. Experiments employ RF (Paul) traps and Penning traps for applications in quantum information processing and precision measurements.

The Ion Storage Group consists of John Bollinger (group leader), Didi Leibfried, Daniel Slichter, and Andrew Wilson (staff physicists, quantum information), James Chou, David Hume and David Leibrandt (staff physicists, precision measurements) and an international group of graduate students and postdoctoral researchers working on experiments in quantum information and precision measurements. Please click on the pictures above for more information on these research areas or see our lists of publications organized by topic: Ion frequency standards, Quantum logic and coherent control, Penning traps and non-neutral plasmas, General and miscellaneous.

We frequently have research opportunities for motivated students and postdocs. Please contact us if you are interested in learning about current opportunities.
