  5. 19. Charge Transport in Semiconductor Nanowire Quantum Devices: From Single Quantum Dots to Topological Superconductors

    Författare :Mingtang Deng; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multiple Andreev reflection; SQUID; Proximity effect; the Josephson effect; Cooper pair; the Kondo effect; the Zeeman effect; Quantum dot; InSb; Nanowires; Transport; Fysicumarkivet A:2013:Deng; Majorana bound state; Yu-Shiba-Rusinov state; Andreev bound state;

    Sammanfattning : This thesis focuses on charge transport in semiconductor InSb nanowire quantum devices, including the electron transport, the hole transport, and the Cooper pair transport. Devices in which InSb semiconductor nanowire quantum dots are coupled with normal metals, superconductors or the proximity effect induced topological superconductors are fabricated and measured.

  7. 20. Quantum Optics with Propagating Microwaves in Superconducting Circuits

    Författare :Io Chun Hoi; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transmon; second-order correlation function; qubit; microwave photons; photon router; superconducting artificial atom; Autler-Townes splitting; quantum network; SQUID; superconducting circuits; cross-Kerr effect; antibunching; Mollow triplet; Josephson junction; quantum optics;

    Sammanfattning : We address recent advances in quantum optics with propagating microwavesin superconducting circuits. This research field exploits on the fact that the coupling between a superconducting artificial atom and propagating microwave photons in a one-dimensional (1D) open transmission line can be made strong enough to observe quantum effects, without using any cavity to confine the microwave photons.
