Abstract

For practical quantum computing, it will be necessary to detect the fluorescence from trapped ions using microscale ion trap chips. We describe the first design, fabrication and assembly of a set of diffractive optics for intimate integration into the trap chip and for coupling this fluorescence into multimode fibers. The design is complicated by the constraints of the ion trap environment. In addition, the choice of available materials is restricted to those compatible with ultrahigh vacuum. The completed optics-ion trap assembly has successfully demonstrated ion trapping, as well as ion shuttling, with no necessary modifications to the trapping and shuttling voltage levels.
