Band Engineering in Cooper-Pair Box: Dispersive Measurements of Charge and Phase
Mika Sillanpaa, Leif Roschier, Teijo Lehtinen +1
Low-frequency susceptibility of the split Cooper-pair box (SCPB) is investigated for use in sensitive measurements of external phase or charge. Depending on the coupling scheme, th…

Direct Observation of Josephson Capacitance
M. A. Sillanpaa, T. Lehtinen, A. Paila +3
The effective capacitance has been measured in the split Cooper pair box (CPB) over its phase-gate bias plane. Our low-frequency reactive measurement scheme allows to probe purely…
