Photon generation in an electromagnetic cavity with a time-dependent boundary
C. M. Wilson, T. Duty, M. Sandberg +3
We report the observation of photon generation in a microwave cavity with a time-dependent boundary condition. Our system is a microfabricated quarter-wave coplanar waveguide cavit…
Fast readout of a single Cooper-pair box using its quantum capacitance
F. Persson, C. M. Wilson, M. Sandberg +1
We have fabricated a single Cooper-pair box (SCB) together with an on-chip lumped element resonator. By utilizing the quantum capacitance of the SCB, its state can be read out by d…
Dressed Relaxation and Dephasing in a Strongly Driven Two-Level system
C. M. Wilson, G. Johansson, T. Duty +3
We study relaxation and dephasing in a strongly driven two-level system interacting with its environment. We develop a theory which gives a straightforward physical picture of the…
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…
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…
In-situ measurement of self-heating in intrinsic tunnelling spectroscopy
V. M. Krasnov, M. Sandberg, I. Zogaj
Using advanced sample engineering we performed simultaneous measurement of intrinsic (interlayer) tunnelling characteristics and in-situ monitoring of temperature in small Bi-2212…
