  2. 2. Quantum optics in constrained geometries

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Björn Hessmo; [2000]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum chemistry; quantum optics; atom optics; complementarity; magnetic traps; laser cooling; quantum information; quantal phases; Kvantkemi; NATURAL SCIENCES Chemistry Theoretical chemistry Quantum chemistry; NATURVETENSKAP Kemi Teoretisk kemi Kvantkemi; Quantum Chemistry; kvantkemi;

    Sammanfattning : When light exhibits particle properties, and when matter exhibits wave properties quantum mechanics is needed to describe physical phenomena. A two-photon source produces nonmaximally entangled photon pairs when the source is small enough to diffract light. It is shown that diffraction degrades the entanglement. LÄS MER

  3. 3. Quantum optics with artificial atoms

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Anton Frisk Kockum; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; surface acoustic waves; transmon; circuit QED; photon detector; parity measurement; quantum stochastic calculus; Quantum optics; artificial atoms; quantum measurement;

    Sammanfattning : Quantum optics is the study of interaction between atoms and photons. In the eight papers of this thesis, we study a number of systems where artificial atoms (here, superconducting circuits emulating the level structure of an atom) enable us to either improve on known concepts or experiments from quantum optics with natural atoms, or to explore entirely new regimes which have not been possible to reach in such experiments.

  4. 4. Quantum Optics and Quantum Information Processing in Rare-Earth-Ion-Doped Crystals

    Detta är en avhandling från Department of Physics, Lund University

    Författare :Nicklas Ohlsson; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Rare-earth ions; Optical processing; Optical storage; Electromagnetism; akustik; optik; Elektromagnetism; optics; acoustics; Photon echo; Quantum optics; Quantum computing; Fysicumarkivet A:2003:Ohlsson;

    Sammanfattning : In this thesis, aspects of the use of cryogenically cooled rare-earth-ion-doped crystals in the fields of quantum optics and quantum information processing are addressed. The experiments and theoretical considerations referred to in this thesis are based on the coherent transient interaction between light and the ions in the crystals. LÄS MER

  5. 5. Quantum photoelectrochemistry : Theoretical studies of organic adsorbates on metal oxides surfaces

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Petter Persson; Uppsala universitet.; [2000]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Chemistry Theoretical chemistry Quantum chemistry; NATURVETENSKAP Kemi Teoretisk kemi Kvantkemi; Quantum Chemistry; kvantkemi; Quantum chemistry; Quantum chemistry; photoelectrochemistry; metal oxide surfaces; organic adsorbates; Kvantkemi;

    Sammanfattning : Interactions between organic molecules and transition metal oxide surfaces have been investigated by means of quantum chemical calculations. The studies have been aimed at understanding electrode-adsorbate interactions in photoelectrochemical devices, such as dye-sensitized solar cells. LÄS MER
