Seminar description:

Using superconducting quantum circuits on silicon chips we make artificial atoms, resonators and waveguides. This "quantum optics on a chip" has become a prospering field of research in recent years. On the one hand, it can be used to study fundamental light-matter coupling similar to traditional quantum optics. On the other hand, these systems provide large potential for solid state based quantum information systems and quantum simulation.

Within the seminar students can give talks on current topics related to solid-state quantum information systems. The seminar is relevant for the special courses on "Superconductivity and Low Temperature Physics". The seminar is suitable for bachelor and master students in the 6. semester and higher. Seminar talks can be given either in English or in German.

List of open topics for seminar talks in SS 2012:

  1. Observation of the dynamical Casimir effect in a superconducting circuit (see C.M. Wilson, Nature, 2011)
  2. Implementation of a Toffoli gate with superconducting circuits (see A. Fedorov, Nature, 2011)
  3. Coherent Frequency Conversion in a Superconducting Artificial Atom with Two Internal Degrees of Freedom (see F. Lecocq, Phys. Rev. Lett., 2012)
  4. On-chip quantum simulation with superconducting circuits (see A.A. Houck, Nature Physics, 2012)
  5. Producing and measuring entanglement between two beams of microwave light (see E. Flurin, arXiv:1204.0732)
  6. Widely tunable, non-degenerate three-wave mixing microwave device operating near the quantum limit (see N. Roch, arXiv:1202.1315)
  7. Demonstrating quantum speed-up in a superconducting two-qubit processor (see A. Dewes, arXiv:1110.5170v1)
  8. Superconducting qubit in waveguide cavity with coherence time approaching 0.1ms (see Chad Rigetti et al., arXiv:1202.5533v1)
  9. Circuit cavity electromechanics in the strong-coupling regime (see J. D. Teufel et al., Nature 2011)
  10. Sideband cooling of micromechanical motion to the quantum ground state (see J. D. Teufel et al., Nature 2011)
