    Sammanfattning : Point defects in semiconductors have been and will continue to be relevant for applications. Shallow defects realize transistors, which power the modern age of information, and in the not-too-distant future, deep-level defects could provide the foundation for a revolution in quantum information processing.

  4. 3. Towards single Ce ion detection in a bulk crystal for the development of a single-ion qubit readout scheme

    Författare :Ying Yan; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2013:Yan; Ultra-violet laser spectroscopy; Single ion detection; Rare-earth-ion-doped crystals; Quantum computing; Laser stabilisation;

    Sammanfattning : The work presented in this thesis was concerned with investigating the relevant spectroscopic properties of Ce ions randomly doped in an Y2SiO5 crystal at low temperatures (around 4 K), in order to develop a technique and an experimental set-up to detect the fluorescence photons emitted by a single Ce ion. The aim of the work was to determine whether a single Ce ion (referred to as the readout ion) can be used as a local probe to sense the quantum state of a neighbouring single-ion qubit via a state-selective interaction between the readout and qubit ion.
