Artificial Neural Network based on SQUIDs: demonstration of network training and operation
F. Chiarello, P. Carelli, M. G. Castellano +1
We propose a scheme for the realization of artificial neural networks based on Superconducting Quantum Interference Devices (SQUIDs). In order to demonstrate the operation of this…
A tunable rf SQUID manipulated as flux and phase qubit
S Poletto, F Chiarello, M G Castellano +4
We report on two different manipulation procedures of a tunable rf SQUID. First, we operate this system as a flux qubit, where the coherent evolution between the two flux states is…
Deep-well ultrafast manipulation of a SQUID flux qubit
M G Castellano, F Chiarello, P Carelli +3
Superconducting devices based on the Josephson effect are effectively used for the implementation of qubits and quantum gates. The manipulation of superconducting qubits is general…
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…
Static flux bias of a flux qubit using persistent current trapping
Maria Gabriella Castellano, Fabio Chiarello, Guido Torrioli +1
Qubits based on the magnetic flux degree of freedom require a flux bias, whose stability and precision strongly affect the qubit performance, up to a point of forbidding the qubit…
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…
Controllable Flux Coupling for the Integration of Flux Qubits
C. Cosmelli, M. G. Castellano, F. Chiarello +4
We show a novel method for controlling the coupling of flux-based qubits by means of a superconducting transformer with variable flux transfer function. The device is realized by i…
