• "Quantum computing in optical microtraps based on the motional states of neutral atoms", Eckert, Mompart, Yi, Schliemann, Bruss, Birkl, Lewenstein, 2002

  Publikation

  We investigate quantum computation with neutral atoms in optical microtraps where the qubit is implemented in the motional states of the atoms, i.e.,...

• "Spin decay and quantum parallelism", Schliemann, Khaetskii, Loss, 2002

  Publikation

  We study the time evolution of a single spin coupled inhomogeneously to a spin environment. Such a system is realized by a single electron spin bound...

  Publikation

  We study the ground-state properties of kinetic-exchange models for (III,Mn)V semiconductors with randomly distributed Mn ions. Our method is embedded...

• "Nonballistic Spin-Field-Effect Transistor", Schliemann, Egues, Loss, 2003

  Publikation

  We propose a spin-field-effect transistor based on spin-orbit coupling of both the Rashba and the Dresselhaus types. Different from earlier proposals,...
