Berry phase in open quantum systems: a quantum Langevin equation approach
Gabriele De Chiara, Artur Lozinski, G. Massimo Palma
The evolution of a two level system with a slowly varying Hamiltonian, modeled as s spin 1/2 in a slowly varying magnetic field, and interacting with a quantum environment, modeled…
Quantum state transfer in imperfect artificial spin networks
M. Paternostro, G. M. Palma, M. S. Kim +1
High-fidelity quantum computation and quantum state transfer are possible in short spin chains. We exploit a system based on a dispersive qubit-boson interaction to mimic XY coupli…
Dynamical entanglement-transfer for quantum information networks
M. Paternostro, W. Son, M. S. Kim +2
A key element in the architecture of a quantum information processing network is a reliable physical interface between fields and qubits. We study a process of entanglement transfe…
Quantum cloning in spin networks
G. De Chiara, R. Fazio, C. Macchiavello +2
We introduce an approach to quantum cloning based on spin networks and we demonstrate that phase covariant cloning can be realized using no external control but only with a proper…
