Superconducting phase qubit based on the Josephson oscillator with strong anharmonicity

A. B. Zorin, F. Chiarello

We propose a superconducting phase qubit on the basis of the radio-frequency SQUID with the screening parameter value ${\beta }_L=(2\pi /{\Phi }_0)L{I}_c\approx 1$, biased by a half flux quantum…
