  1. 1. Parametrically pumped superconducting circuits

    Author : Philip Krantz; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SQUID; circuit quantum electrodynamics; Josephson junction; Superconducting circuits; resonators; parametric oscillators; quantum bit; pumpistor; quantum information;

    Abstract : In this licentiate thesis, I present the design, fabrication, and characterization of superconducting parametric resonators, for use in quantum information processing. These devices are quarter-wavelength coplanar waveguide resonators (~5 GHz), terminated at one end by a non-linear inductance provided by a SQUID (superconducting quantum interference device).

  2. 2. Quantum Optics with Propagating Microwaves in Superconducting Circuits

    Author : Io Chun Hoi; Chalmers University of Technology; []
    Keywords : 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;

    Abstract : 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.

  3. 3. Quantum acoustics with superconducting circuits

    Author : Gustav Andersson; Chalmers University of Technology; []
    Keywords : cluster states; two-mode squeezing; SAW; giant atoms; two-level systems; hybrid quantum systems; quantum acoustics; circuit QED; superconducting qubits; surface acoustic wave;

    Abstract : The past 20 years has seen rapid developments in circuit quantum electrodynamics, where superconducting qubits and resonators are used to control and study quantum light-matter interaction at a fundamental level. The development of this field is strongly influenced by quantum information science and the prospect of realizing quantum computation, but also opens up opportunities for combinations of different physical systems and research areas.

  4. 4. Waveguide Quantum Electrodynamics in Superconducting Circuits

    Author : Emely Wiegand; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; Superconducting Qubits; Artificial Atoms; Waveguide Quantum Electrodynamics; Circuit Quantum Electrodynamics; Quantum Optics;

    Abstract : In the last two decades, the field of circuit quantum electrodynamics, that studies the interaction between superconducting qubits and 1-dimensional waveguides, has been of great interest. It provides a great potential to build quantum devices, which are important for quantum computing, quantum communication and quantum information. READ MORE

  5. 5. Quantum information processing with tunable and low-loss superconducting circuits

    Author : Andreas Bengtsson; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; quantum information; circuit quantum electrodynamics; superconducting circuits; high coherence; parametric modulation;

    Abstract : The perhaps most promising platform for quantum information processing is the circuit-QED architecture based on superconducting circuits representing quantum bits. These circuits must be made with low losses so that the quantum information is retained for as long as possible. READ MORE
