Single rare earth ions as a new platform for quantum optics — •Emanuel Eichhammer, Tobias Utikal, Stephan Götzinger, and Vahid Sandoghdar — Max Planck Institute for the Science of Light and Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), D-91058 Erlangen, Germany
Embedding single quantum emitters in the solid state promises improved accessibility and scalability for many emerging quantum technologies such as quantum memories and networks. Pr3+ ions doped in a Y2SiO5 crystal have already been used in many interesting ensemble experiments. The spectrally narrow features, the availability of a hyperfine-split ground state and exceptionally long coherence times make this system an ideal platform for quantum information processing. Here we show the successful selection of a single Praseodymium ion from an inhomogeneously broadened ensemble, via two different transitions at 488 nm and 606 nm [1,2]. We present measurements of the second order auto-correlation function g(2), studies of the hyperfine transitions and resonance linewidths, fluorescence lifetime measurements and emission spectra of a single ion. We discuss future plans for the enhancement of the fluorescence signal by coupling single ions to microcavities.
