Non-equilibrium probing of two-level charge fluctuators using the step response of a single electron transistor
A. Pourkabirian, M. V. Gustafsson, G. Johansson +2
We report a new method to study two level fluctuators (TLFs) by measuring the offset charge induced after applying a sudden step voltage to the gate electrode of a single electron…
Deterministic loading and phase shaping of microwaves onto a single artificial atom
W. -J. Lin, Y. Lu, P. Y. Wen +12
Loading quantum information deterministically onto a quantum node is an important step towards a quantum network. Here, we demonstrate that coherent-state microwave photons, with a…
Excess dissipation in a single-electron box: The Sisyphus resistance
F. Persson, C. M. Wilson, M. Sandberg +2
We present measurements of the ac response of a single-electron box (SEB). We apply an rf signal with a frequency larger than the tunneling rate and drive the system out of equilib…
Anticorrelation between temperature and fluctuations in moderately damped Josephson junctions
V. M. Krasnov, T. Golod, T. Bauch +1
We study the influence of dissipation on the switching current statistics of moderately damped Josephson junctions. Different types of both low- and high- junctions with cont…
Scattering of coherent states on a single artificial atom
B. Peropadre, J. Lindkvist, I. -C. Hoi +4
In this work we theoretically analyze a circuit QED design where propagating quantum microwaves interact with a single artificial atom, a single Cooper pair box. In particular, we…
Coherence times of dressed states of a superconducting qubit under extreme driving
C. M. Wilson, T. Duty, F. Persson +3
In this work, we measure longitudinal dressed states of a superconducting qubit, the single Cooper-pair box, and an intense microwave field. The dressed states represent the hybrid…
