چکیده
Efficient collection of trapped ion fluorescence is critical for high-fidelity qubit detection and ion-photon logical interconnects in ion trap quantum information processing. The expected size of future many-ion processors place scalability requirements for high efficiency optical collection systems. We report the development and testing of a microfabricated planar ion trap with an integrated high numerical aperture micromirror for improved photon collection. The design is tolerant of ion misalignment and is inherently scalable to large arrays of detection mirrors in a single device. We demonstrate stable trapping and transport of Ca ions over a 0.63 NA micromirror and observe a factor of 1.9 enhancement in photon collection. PACS numbers: 37.10.Ty, 03.67.Lx, 42.15.Eq

Microfabricated surface ion trap on a high-finesse optical mirror.
A novel approach to optics integration in ion traps is demonstrated based on a surface electrode ion trap that is microfabricated on top of a dielectric mirror. Additional optical losses due to fabrication are found to be as low as 80 ppm for light at 422 nm. The integrated mirror is used to demonstrate light collection from, and imaging of, a single Sr88(+) ion trapped 169±4 μm above the mirror.

متن کاملExperimental Methods for Trapping Ions Using Microfabricated Surface Ion Traps
Ions trapped in a quadrupole Paul trap have been considered one of the strong physical candidates to implement quantum information processing. This is due to their long coherence time and their capability to manipulate and detect individual quantum bits (qubits). In more recent years, microfabricated surface ion traps have received more attention for large-scale integrated qubit platforms. This...
