Fused Silica Ion Trap Chip with Efficient Optical Collection System for Timekeeping, Sensing, and Emulation.

摘要

The objective of this program was to demonstrate a cost-effective, scalable, rapid manufacturing system to produce advanced semi-custom and custom atom/ion chips for the scientific and defense communities. Specifically, we fabricated three-dimensional ion microtraps whereby the ion trap platform and the optical interface platform are integrated within a single glass substrate. The integration of optics with a chip trap pursued in this program has the potential to critically transform the use of ion traps for the collection of atomic fluorescence for motion/force sensors through Doppler velocimetry; and for the efficient collection of single photons from trapped ions for applications in fast single photon sources, quantum repeater circuitry, and high fidelity remote entanglement of atoms for quantum information protocols. We delivered to our academic partners, several three-dimensional ion microtraps of a type, geometry, and capability not previously available in a small form factor. Oblate Paul microtraps that will be used for the creation of two-dimensional coulomb crystals of ions for quantum simulations were fabricated for UCLA.
