state generation of three Josephson qubits in presence of bosonic baths
S. Spilla, R. Migliore, M. Scala +1
We analyze an entangling protocol to generate tripartite Greenberger-Horne-Zeilinger states in a system consisting of three superconducting qubits with pairwise coupling. The dynam…
Resonant effects in a SQUID qubit subjected to non adiabatic changes
F. Chiarello, S. Spilla, M. G. Castellano +5
By quickly modifying the shape of the effective potential of a double SQUID flux qubit from a single-well to a double-well condition, we experimentally observe an anomalous behavio…
Entanglement sudden death and sudden birth in two uncoupled spins
E. Ferraro, A. Napoli, M. Guccione +1
We investigate the entanglement evolution of two qubits interacting with a common environment trough an Heisenberg XX mechanism. We reveal the possibility of realizing the phenomen…
Non-Markovian dissipative dynamics of two coupled qubits in independent reservoirs: a comparison between exact solutions and master equation approaches
E. Ferraro, M. Scala, R. Migliore +1
The reduced dynamics of two interacting qubits coupled to two independent bosonic baths is investigated. The one-excitation dynamics is derived and compared with that based on the…
Exact dynamics of XX central spin models
M. A. Jivulescu, E. Ferraro, A. Napoli +1
The dynamical behavior of a star network of spins, wherein each of N decoupled spins interact with a central spin through non uniform Heisenberg XX interaction is exactly studied.…
Non-Markovian dynamics of a single electron spin coupled to a nuclear spin bath
E. Ferraro, H. -P. Breuer, A. Napoli +2
We apply the time-convolutionless (TCL) projection operator technique to the model of a central spin which is coupled to a spin bath via nonuniform Heisenberg interaction. The seco…
