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 WS 2014/2015:

  1. Defining and detecting quantum speedup (see Science 345, 420 (2014))
  2. Bidirectional and efficient conversion between microwave and optical light (see Nature Physics 10, 321–326 (2014))
  3. Observation of a Dissipation-Induced Classical to Quantum Transition (see Phys. Rev. X 4, 031043 (2014))
  4. Unconditional quantum teleportation between distant solid-state quantum bits (see Science 345,532 (2014))
  5. Tracking photon jumps with repeated quantum non-demolition parity measurements (see Nature 511, 444–448 (2014))
  6. Protecting a spin ensemble against decoherence in the strong-coupling regime of cavity QED (see Nature Physics 10, 720-724 (2014))
  7. Quantum limited amplification and entanglement in coupled nonlinear resonators (see Phys. Rev. Lett. 113, 110502 (2014))
