Decoherence and gate performance of coupled solid state qubits
Markus J. Storcz, Frank K. Wilhelm
Solid state quantum bits are promising candidates for the realization of a {\em scalable} quantum computer. However, they are usually strongly limited by decoherence due to the man…
Nonlinear cotunneling through an artificial molecule
Udo Hartmann, Frank K. Wilhelm
We study electron transport through a system of two lateral quantum dots coupled in series. We consider the case of weak coupling to the leads and a bias point in the Coulomb block…
Kondo excitons in self-assembled quantum dots
A. O. Govorov, K. Karrai, R. J. Warburton
We describe novel excitons in quantum dots by allowing for an interaction with a Fermi sea of electrons. We argue that these excitons can be realized very simply with self-assemble…
Decoherence of interacting electrons in disordered conductors: on the relation between influence functional and diagrammatic approaches
Jan von Delft
We establish a connection between the influence functional approach of Golubev and Zaikin (GZ) and Keldysh diagrammatic perturbation theory for calculating the decoherence time of…
Two pairing parameters in superconducting grains
M. Schechter, J. von Delft, Y. Imry +1
Unlike bulk superconductivity, where one energy scale, the energy gap, characterizes pairing correlations, we show that in small superconducting grains there exist two different su…
Supercurrent-carrying density of states in diffusive mesoscopic Josephson weak links
Tero T. Heikkilä, Jani Särkkä, Frank K. Wilhelm
Recent experiments have demonstrated the nonequilibrium control of the supercurrent through diffusive phase-coherent normal-metal weak links. The experimental results have been acc…
