  1. 1. Distortion and attenuation free gain-assisted Superluminal Propagtion in a Rare-Earth Doped Crystal

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Antonius Johannes Renders; [2023]
    Keywords : Fast Light; Superluminal Propagation; Negative group velocity; Rare earth; Physics and Astronomy;

    Abstract : A light pulse that travels through a narrow spectral window, i.e. a frequency range of low absorption, within a strongly absorbing frequency range will be delayed due to strong dispersion. READ MORE

  3. 2. Formation of Eu II spectral features in magnetic chemically peculiar stars

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Luca Schmidt; [2020]
    Keywords : ;

    Abstract : The advancing resolution of modern spectrometers uncovers increasingly detailed spectral features in astrophysical observations which can be attributed to properties of the energy structure of the corresponding atomic systems such as fine, hyperfine and Zeeman splitting. At the same time, increasing computational power enables us to include these quantum mechanical interactions on different levels of sophistication in our theoretical atomic structure calculations.

  4. 3. Monte Carlo simulation of the spatial response function of a SPECT measurement device for nuclear fuel bundles

    University essay from Stockholms universitet/Fysikum

    Author : Emilie Dul; [2017]
    Keywords : Monte Carlo MCNPX Safeguards;

    Abstract : The PGET device is currently being developed for partial-defect verication purposes on nuclear fuel assemblies. It Comprises CdTe detector elements in a heavy tungsten-alloy collimator, for which collimator slit openings define the field-of-view. READ MORE

  5. 4. Influence of Ion-Ion Interactions on Single Qubit State Transfer Fidelities

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

    Author : Sofia Borgå; [2015]
    Keywords : Physics and Astronomy;

    Abstract : Experimental single qubit gate fidelities in the rare-earth quantum computing (REQC) scheme was found to be lower than predicted by simulation of the optical Bloch equations for the system. The cause was believed to be excitation-induced frequency shifts (EFS), so this BSc thesis investigates a model for EFS in Eu:YSO where stochastic frequency shifts are imposed on the ions. READ MORE

  6. 5. High delity operations in a europium doped inorganic crystal

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Pernilla Helmer; [2015]
    Keywords : quantum information; Eu; europium; hole burning; quantum memory; qubit; Physics and Astronomy;

    Abstract : The computer has since it was invented become a most crucial tool for scientists in all fields. It has however severe limitations when it comes to e.g. simulating quantum systems, a task quantum computers might be able to perform. READ MORE
