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…
Landau-Zener interferometry with superconducting qubits
Mika Sillanpaa, Teijo Lehtinen, Antti Paila +2
Quantum-mechanical systems having two discrete energy levels are ubiquitous in nature. For crossing energy levels, depending on how fast they approach each other, there is a possib…
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…
