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" and "Applied Superconductivity". 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 2014:

  1. Design and characterization of a lumped element single-ended superconducting microwave parametric amplifier with on-chip flux bias line (see Phys. Rev. Lett. 111, 080502 (2013))
  2. Reduction of the radiative decay of atomic coherence in squeezed vacuum (see Nature 499, 62 (2013))
  3. Observation of a Dissipation-Induced Classical to Quantum Transition (see arXiv:1312.2963)
  4. Autonomously stabilized entanglement between two superconducting quantum bits (see Nature 504, 419 (2013))
  5. Observing single quantum trajectories of a superconducting quantum bit (see Nature 502, 211 (2013))
