  1. 1. Parametric interactions with signals and the vacuum

    Författare :Michael Roger Andre Simoen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; vacuum; circuit-QED; interferometer; SQUID; dynamical Casimir effect; multimode resonator; pumpistor; mode conversion; superconducting circuits; parametric amplification;

    Sammanfattning : In this thesis I present different experiments on superconducting circuits exploring parametric interactions with external signals and the vacuum in the microwave regime. These parametric processes are the result of the periodic modulation of a property of a system which results in different interactions. LÄS MER

  4. 3. Quantum optics and relativistic motion with superconducting circuits

    Författare :Joel Lindkvist; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Superconducting microwave circuits provide a versatile platform for studying quantum optics with artificial atoms, mainly motivated by applications in quantum information. In addition, the circuits are promising for simulation of relativistic phenomena. This thesis is based on theoretical work along both these lines. LÄS MER
