Reading-out the state inductively and microwave spectroscopy of an interferometer-type charge qubit
D. Born, V. I. Shnyrkov, W. Krech +5
We implemented experimentally an interferometer-type charge qubit consisting of a single-Cooper-pair transistor closed by a superconducting loop that is in flip-chip configuration…
Observation of macroscopic Landau-Zener transitions in a superconducting device
A. Izmalkov, M. Grajcar, E. Il'ichev +7
A two-level system traversing a level anticrossing has a small probability to make a so-called Landau-Zener (LZ) transition between its energy bands, in deviation from simple adiab…
Josephson effect as a measure of quantum fluctuations in the cuprates
R. Hlubina, M. Grajcar, J. Mraz
Quantitative analysis of the Josephson effect is shown to provide direct information about phase fluctuations in the superconducting banks. Applying the analysis to the cuprates, s…
Low-frequency measurement of the tunneling amplitude in a flux qubit
M. Grajcar, A. Izmalkov, E. Il'ichev +13
We have observed signatures of resonant tunneling in an Al three-junction qubit, inductively coupled to a Nb LC tank circuit. The resonant properties of the tank oscillator are sen…
