    Abstract : The research of this Ph. D. thesis is in the field of Quantum Computation and Quantum Information. A key problem in this field is the fragile nature of quantum states. READ MORE

  3. 3. Superconducting qubits - measurement, entanglement, and noise

    Author : Lars Tornberg; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum Electric Circuits; Open Quantum Systems; Quantum Optics; Quantum Computing; Superconducting Qubits; Quantum Measurement;

    Abstract : In the early 1980’s, it was suggested that a computer obeying the laws of quantum mechanics would be able to solve problems beyond the capabilities of a classical computer. The novel ways in which such a quantum computer works relies on the quantum properties of the quantum bits (qubits) used to store the information. READ MORE

  4. 4. Dynamics of Quantum Correlations with Photons : Experiments on bound entanglement and contextuality for application in quantum information

    Author : Elias Amselem; Mohamed Bourennane; Antonio Acín; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Quantum information; quantum optics; foundations of quantum mechanics; entanglement; non-contextuality; Kochen-Specker theorem; parametric down-conversion; quantum state engineering; fysik; Physics;

    Abstract : The rapidly developing interdisciplinary field of quantum information, which merges quantum and information science, studies non-classical aspects of quantum systems. These studies are motivated by the promise that the non-classicality can be used to solve tasks more efficiently than classical methods would allow. READ MORE

  5. 5. Measuring quantum systems with a tunnel junction

    Author : Joachim Wabnig; Jörgen Rammer; Ulrich Eckern; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; quantum mechanics; quantum measurement; tunnel junction; qubit; nanomechanics; noise; Physics; Fysik;

    Abstract : This thesis is concerned with employing the statistics of charge transfer in a conductor as a tool for quantum measurement. The physical systems studied are electronic devices made by nanoscale manufacturing techniques. In this context quantum measurement appears not as a postulate, but as physical process. READ MORE
