  1. 1. Engineering superconducting qubits : towards a quantum machine

    Författare :Joachim Sjöstrand; Anders Karlhede; Denis Vion; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Physics; Fysik;

    Sammanfattning : A quantum computer is an information processing machine, much like an ordinary classical computer, but its function is based on quantum mechanical principles. To be able to construct such a machine would be a fantastic accomplishment---to have total control over a quantum system is a dream for both physicists and science-fiction enthusiasts. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  3. 3. Read-out of superconducting qubits - a quantum measurement process

    Författare :Lars Tornberg; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; superconducting qubits; single Cooper Pair box; quantum measurements; quantum electrical circuits; quatum computing;

    Sammanfattning : In this work we consider measurements on quantum systems emphasizingon read-out of superconducting qubits. The qubit is always coupled to anenvironment, containing a macroscopic number of degrees of freedom. Thisperturbs the qubit and destroys the phase coherence of the quantum state. LÄS MER

  4. 4. Quantum acoustics with superconducting circuits

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

    Sammanfattning : 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.

  5. 5. Waveguide Quantum Electrodynamics in Superconducting Circuits

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

    Sammanfattning : 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. LÄS MER
