Working Group Theory of Quantum State Engineering and Quantum Information


Head: Prof. Dr. Alexander Shnirman

We study

  • Quantum state engineering in Josephson and spin systems
  • Microscopic decoherence sources in Josephson and spin qubits
  • Geometric phases and geometric pumping
  • Charge solitons in one-dimensional Josephson arrays
