- Abstract summary: We have experimentally performed the single-site optical spectroscopy and optical addressing of a single rare-earth atom in an amorphous silica optical fiber at room temperature.
The ability to address single RE atoms at room temperature provides a very stable and cost-effective technical platform for the realization of a solid-state system for a large-scale quantum optical network.

- Abstract: Rare-earth (RE) atoms in solid-state materials are attractive components for
photonic quantum information systems because of their coherence properties even
in high-temperature environments. We have experimentally performed the
single-site optical spectroscopy and optical addressing of a single RE atom in
an amorphous silica optical fiber at room temperature. The single-site optical
spectroscopy of the tapered RE-doped fiber shows nonresonant emission lines
similar to those seen in the case of an unstructured fiber and the
autocorrelation function of photons emitted from the fiber shows the
antibunching effect due to the spatial isolation given by the tapered fiber
structure. The ability to address single RE atoms at room temperature provides
a very stable and cost-effective technical platform for the realization of a
solid-state system for a large-scale quantum optical network and other quantum
technologies based on a large number of spectral channels from visible to
midinfrared wavelengths.

Multiple stationary states of the FPI cavity field with different spectra are possible at realistic conditions, for example, in the FPI with the photonic crystal cavity and the semiconductor-doped glass nonlinear medium.
