Consistency of ground state and spectroscopic measurements on flux qubits
A. Izmalkov, S. H. W. van der Ploeg, S. N. Shevchenko +5
We compare the results of ground state and spectroscopic measurements carried out on superconducting flux qubits which are effective two-level quantum systems. For a single qubit a…
Resonant excitations of single and two-qubit systems coupled to a tank circuit
S. N. Shevchenko, S. H. W. van der Ploeg, M. Grajcar +3
The interaction of flux qubits with a low frequency tank circuit is studied. It is shown that changes in the state of the interacting qubits influence the effective impedance of th…
Distinguishing quantum from classical oscillations in a driven phase qubit
S. N. Shevchenko, A. N. Omelyanchouk, A. M. Zagoskin +2
Rabi oscillations are coherent transitions in a quantum two-level system under the influence of a resonant perturbation, with a much lower frequency dependent on the perturbation a…
Pseudo-Rabi oscillations in superconducting flux qubits in the classical regime
A. N. Omelyanchouk, S. N. Shevchenko, A. M. Zagoskin +2
Nonlinear effects in mesoscopic devices can have both quantum and classical origins. We show that a three-Josephson-junction (3JJ) flux qubit in the _classical_ regime can produce…
Multiphoton transitions between energy levels in a phase-biased Cooper-pair box
V. I. Shnyrkov, Th. Wagner, D. Born +5
We investigated both theoretically and experimentally dynamic features of a phase-biased charge qubit consisting of a single-Cooper-pair transistor closed by a superconducting loop…
