  1. 1. Time dependent processes incavity QED

    Författare :Jonas Larson; KTH; []
    Nyckelord :cavity QED; state preparation; non-classical; Jaynes-Cummings model; Fock state; measurement;

    Sammanfattning : Cavity quantum electrodynamics (QED) has become one of themost successful tools for quantum information processing, butalso for the study of other pure quantum effects. In thisthesis we investigate one such system, the micromaser; an atomtraverse a cavity and interacts with the quantized modes of thecavity field. LÄS MER

    Sammanfattning : Superconducting circuits are well established tools for quantum sensing anda promising new platform for quantum computing. Typically these quantumcircuits operate at microwave frequencies where the thermal noise at 10mK in a dilution refrigerator is small compared to the ground-state energy. LÄS MER

  4. 3. Extended Jaynes-Cummings Models In Cavity Qed

    Författare :Jonas Larson; Stig Stenholm; Peter L. Knight; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Optics; Optics; Optik;

    Sammanfattning : Due to the improvement within cavity quantum electrodynamics experiments during the last decades, what was former seen as 'toy models' are today realized in laboratories. A controlled isolated coherent evolution of one or a few atoms coupled to a single mode inside a cavity is achievable. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microwave photon detection; Quantum optics; open quantum systems.; tunable cavity; cross-Kerr effect; circuit QED;

    Sammanfattning : Microwave quantum optics using superconducting circuits, also known as circuit QED, is a recent and promising field to study light-matter interactions at the fundamental level. In this field, artificial atoms made of superconducting elements interact with microwave photons routed through one dimensional transmission lines. LÄS MER
