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

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

   Abstract : 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. READ MORE

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

   Author : Lars Tornberg; Chalmers tekniska högskola; []
   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

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

   Author : Lars Tornberg; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; superconducting qubits; single Cooper Pair box; quantum measurements; quantum electrical circuits; quatum computing;

   Abstract : 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. READ MORE

6. 4. Quantum acoustics with superconducting circuits

   Author : Gustav Andersson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; superconducting qubits; cluster states; SAW; two-level systems; circuit QED; giant atoms; two-mode squeezing; surface acoustic wave; quantum acoustics; hybrid quantum systems;

   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.

7. 5. Waveguide Quantum Electrodynamics in Superconducting Circuits

   Author : Emely Wiegand; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; 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
