• "Driven tunneling dynamics: Bloch-Redfield theory versus path-integral approach", Hartmann, Goychuk, Grifoni, Hänggi, 2000

  Publication

  In the regime of weak bath coupling and low temperature we demonstrate numerically for the spin-boson dynamics the equivalence between two widely used...

• "Double-occupancy errors, adiabaticity, and entanglement of spin qubits in quantum dots", Schliemann, Loss, MacDonald, 2001

  Publication

  Quantum gates that temporarily increase singlet-triplet splitting in order to swap electronic spins in coupled quantum dots lead inevitably to a...

  Publication

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