dc.description | Entanglement between single spins and photons is an important resource in quantum information science, e.g. in quantum networking. Rare-earth ions in dielectric crystals have emerged as a promising candidate for this task. Rare-earth ion doped solids have been used so far mostly as ensemble-based quantum memories. However, they also feature promising properties for single ion detection and manipulation, such as long-lived spins, narrow optical transitions and preservation of coherence properties when inserted in nanostructures. Because of the long lifetimes of the optical t |
dc.description.abstract | The goal of this master thesis was to take initial steps towards cavity-enhanced detection of single rare-earth ions in the solid state. A fibre microcavity set-up for use with Praseodymium-doped nanocrystals was designed, built and characterised with light at 606 nm, with the aim to achieve Purcell enhancement. The cavity has a finesse of 3374, linewidth of 14 GHz and FSR of 80 THz. In addition, fluorescence and linewidth measurements of Er3+:Y2O3 nanocrystals at room temperature were taken in the telecom range. A primary fluorescence peak at 1535.424 nm with FWHM of 171 GHz was observed, corresponding to the Er3+:4I13/2 ? 4I15/2 transition, and a secondary peak at 1536.851 nm. A population decay time T1 of 13.3 ms was measured. |
