Coherent oscillations in a superconducting tunable flux qubit manipulated without microwaves
S. Poletto, F. Chiarello, M. G. Castellano +6
We experimentally demonstrate the coherent oscillations of a tunable superconducting flux qubit by manipulating its energy potential with a nanosecond-long pulse of magnetic flux.…
Temperature dependence of coherent oscillations in Josephson phase qubits
J. Lisenfeld, A. Lukashenko, M. Ansmann +2
We experimentally investigate the temperature dependence of Rabi oscillations and Ramsey fringes in superconducting phase qubits driven by microwave pulses. In a wide range of temp…
Enhanced Macroscopic Quantum Tunneling in BiSrCaCuO Intrinsic Josephson Junction Stacks
X. Y. Jin, J. Lisenfeld, Y. Koval +3
We have investigated macroscopic quantum tunneling in BiSrCaCuO intrinsic Josephson junctions at millikelvin temperatures using microwave irradiation. Measureme…
Laser Scanning Microscopy of HTS Films and Devices
A. P. Zhuravel, A. G. Sivakov, O. G. Turutanov +3
The work describes the capabilities of Laser Scanning Microscopy (LSM) as a spatially resolved method of testing high_Tc materials and devices. The earlier results obtained by the…
Quantum dissociation of a vortex-antivortex pair in a long Josephson junction
M. V. Fistul, A. Wallraff, Y. Koval +3
We report a theoretical analysis and experimental observation of the quantum dynamics of a single vortex-antivortex (VAV) pair confined in a long narrow annular Josephson junction.…
