Radio-Frequency Method for Investigation of Quantum Properties of Superconducting Structures
E. Il'ichev, A. Yu. Smirnov, M. Grajcar +7
We implement the impedance measurement technique (IMT) for characterization of interferometer-type superconducting qubits. In the framework of this method, the interferometer loop…
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…
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…
Continuous Monitoring of Rabi Oscillations in a Josephson Flux Qubit
E. Il'ichev, N. Oukhanski, A. Izmalkov +7
Under resonant irradiation, a quantum system can undergo coherent (Rabi) oscillations in time. We report evidence for such oscillations in a _continuously_ observed three-Josephson…
