A self-referenced single-electron quantized-current source
Lukas Fricke, Michael Wulf, Bernd Kaestner +8
With the anticipated redefinition of the international system of units (SI) the base units will be linked to fundamental constants of nature [1]. As for the electrical base unit "A…
Counting statistics for electron capture in a dynamic quantum dot
Lukas Fricke, Michael Wulf, Bernd Kaestner +10
We report non-invasive single-charge detection of the full probability distribution of the initialization of a quantum dot with electrons for rapid decoupling from an ele…
Quantum dynamics in a camel-back potential of a dc SQUID
E. Hoskinson, F. Lecocq, N. Didier +7
We investigate the quantum dynamics of a quadratic-quartic anharmonic oscillator formed by a potential well between two potential barriers. We realize this novel potential shape wi…
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…
Quasi-particle transitions in charge-phase qubits probed by rf oscillations
J. Könemann, H. Zangerle, B. Mackrodt +2
We investigated transitions in Al charge-phase qubits of SQUID-configuration inductively coupled to an rf tank circuit that made it possible to read out the state by measuring the…
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…
