Rice team develops a 3D ion trap for quantum research

Researchers at Rice University developed a three-dimensional ion trap with collaborators from Duke University and Translume Inc.

The device uses electric fields to hold charged atoms and lasers to control them, allowing scientists to study systems that are difficult to model with conventional computers.

The design works with heavy ions such as ytterbium, expanding the options for monolithic traps, which are built as a single structure.

Earlier designs could use lighter ions but faced engineering challenges with heavier ones.

After two prototypes developed problems, the team redesigned the trap to improve heat dissipation and reduce unwanted ion movement and heating.

The researchers tested the finished devices, and their measurements matched earlier computer simulations.

The trap could make experiments easier to reproduce and help laboratories investigate complex processes, including charge transfer during photosynthesis.

Researchers may also adapt its engineering approach for other ion traps, but no specific next steps are stated.
