Acoustic spectral hole-burning in a two-level system ensemble
Gustav Andersson, André Luiz Oliveira Bilobran, Marco Scigliuzzo +3
Microscopic two-level system (TLS) defects at dielectric surfaces and interfaces are among the dominant sources of loss in superconducting quantum circuits, and their properties ha…
Nonclassical microwave radiation from the dynamical Casimir effect
J. R. Johansson, G. Johansson, C. M. Wilson +2
We investigate quantum correlations in microwave radiation produced by the dynamical Casimir effect in a superconducting waveguide terminated and modulated by a superconducting qua…
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…
Characterization of an entangled system of two superconducting qubits using a multiplexed capacitance readout
M. D. Shaw, J. F. Schneiderman, J. Bueno +3
We characterize a pair of Cooper-pair boxes coupled with a fixed capacitor using spectroscopy and measurements of the ground-state quantum capacitance. We use the extracted paramet…
Observation of quantum capacitance in the Cooper-pair transistor
T. Duty, G. Johansson, K. Bladh +3
We have fabricated a Cooper-pair transistor (CPT) with parameters such that for appropriate voltage biases, the sub-gap charge transport takes place via slow tunneling of quasipart…
Two-dimensional arrays of low capacitance tunnel junctions: general properties, phase transitions and Hall effect
P. Delsing, C. D. Chen, D. B. Haviland +2
We describe transport properties of two-dimensional arrays of low capacitance tunnel junctions, such as the current voltage characteristic and its dependence on external magnetic f…
