Abstract
Integration of fiber optics may play a critical role in the development of quantum information processors based on trapped ions, atoms, and quantum dots. Fibers could help enable a scalable and efficient means of collecting light from and delivering light to the qubits, as well as for enabling optical microcavities coupled to trapped ions and atoms. We demonstrate trapping of 24Mg+ ions in a surface-electrode trap that includes an integrated optical fiber for detecting fluorescence. The ion can be positioned between 80 and 100 υm from the tip of the fiber using an adjustable rf-pseudopotential. Fluorescence photons at 280~nm are detected through the fiber with a collection numerical aperture of 0.37, and total collection efficiency of 2.1%.Citation
