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.…
An Optimal Tunable Josephson Element for Quantum Computing
F. Chiarello, M. G. Castellano, G. Torrioli +6
We introduce a three-junction SQUID that can be effectively used as an optimal tunable element in Josephson quantum computing applications. This device can replace the simple dc SQ…
Catastrophe observation in a Josephson junction system
M. G. Castellano, F. Chiarello, R. Leoni +9
We report on a direct quantitative comparison between Thom's general catastrophe theory for systems presenting discontinuous behavior and experimental reality. It is demonstrated t…
Characterization of a fabrication process for the integration of superconducting qubits and RSFQ circuits
Maria Gabriella Castellano, Leif Gronberg, Pasquale Carelli +7
In order to integrate superconducting qubits with rapid-single-flux-quantum (RSFQ) control circuitry, it is necessary to develop a fabrication process that fulfills at the same tim…
Superconducting tunable flux qubit with direct readout scheme
Fabio Chiarello, Pasquale Carelli, Maria Gabriella Castellano +6
We describe a simple and efficient scheme for the readout of a tunable flux qubit, and present preliminary experimental tests for the preparation, manipulation and final readout of…
