Modeling of quasiparticle-induced excitations of a Josephson charge-phase qubit
J. Könemann, H. Zangerle, B. Egeling +4
We have analyzed quasiparticle transitions in an Al charge-phase qubit inducing a dynamic change of the qubit states. The time-averaged mixed state is related to the strong couplin…
Ground-state characterization of Nb charge-phase Josephson qubits
Hermann Zangerle, Jens Könemann, Brigitte Mackrodt +5
We present investigations of Josephson charge-phase qubits inductively coupled to a radio-frequency driven tank-circuit enabling the readout of the states by measuring the Josephso…
Shot noise in resonant tunneling through a zero-dimensional state with a complex energy spectrum
A. Nauen, F. Hohls, J. Konemann +1
We investigate the noise properties of a GaAs/AlGaAs resonant tunneling structure at bias voltages where the current characteristic is determined by single electron tunneling. We d…
Measurement of the energy dependence of phase relaxation by single electron tunneling
P. König, J. Könemann, T. Schmidt +3
Single electron tunneling through a single impurity level is used to probe the fluctuations of the local density of states in the emitter. The energy dependence of quasi-particle r…
Resonant tunneling through zero-dimensional impurity states: Effects of a finite temperature
P. König, U. Zeitler, J. Könemann +2
We have performed temperature dependent tunneling experiments through a single impurity in an asymmetric vertical double barrier tunneling structure. In particular in the charging…
