Fiber Optics in Surface-Electrode Ion Traps

A scalable and efficient method for light collection from point sources of fluorescence is demonstrated. Multi-mode crystal-structured optical fibers are integrated into a surface-electrode rf Paul trap for collection of fluorescence photons emitted from trapped Mg+ ions. This optical collection technique has applications for scalable quantum computation. Applications to light delivery, cavity QED, and potential future improvements will also be discussed.
