Quantum dynamics in a camel-back potential of a dc SQUID
E. Hoskinson, F. Lecocq, N. Didier +7
We investigate the quantum dynamics of a quadratic-quartic anharmonic oscillator formed by a potential well between two potential barriers. We realize this novel potential shape wi…
Evidence of two-dimensional macroscopic quantum tunneling of a current-biased DC-SQUID
F. Balestro, J. Claudon, J. P. Pekola +1
The escape probability out of the superconducting state of a hysteretic DC-SQUID has been measured at different values of the applied magnetic flux. At low temperature, the escape…
Entangled states in a Josephson charge qubit coupled to a superconducting resonator
O. Buisson, F. W. J. Hekking
We study the dynamics of a quantum superconducting circuit which is the analogue of an atom in a high-Q cavity. The circuit consists of a Josephson charge qubit coupled to a superc…
Plasma Waves in Anisotropic Superconducting Films Below and Above the Plasma Frequency
Mauro M. Doria, Gilberto Hollauer, F. Parage +1
We consider wave propagation inside an anisotropic superconducting film sandwiched between two semi-infinite non-conducting bounding dieletric media such that along the c-axis, per…
