Quantum and Solid State Theory Group 
Saarland University

Group Research Goals

We are performing research at the intersection of solid state physics and quantum information. Specifically, we are interested in the physics of nanoscale devices with quantum functionality. Our research is theoretical but is carried out in close collaboration with experimental researchers around the world. 

Current projects:
  • Superconducting quantum bits
  • Quantum bits based on semiconductor nanostructures
  • Optimal quantum gates in imperfect qubits
  • The physics of the measurement process with nonlinear detectors
  • Quantum phenomena in nonlinear systems, e.g. dynamical tunneling
  • Scalable architectures for quantum computers with realistic error thresholds
  • Circuit quantum electrodynamics
  • Decoherence from structured environments
A presentation that introduces research in the Quantum Devices Theory group is here.
