Bipartite entanglement and entropic boundary law in lattice spin systems
Alioscia Hamma, Radu Ionicioiu, Paolo Zanardi
We investigate bipartite entanglement in spin-1/2 systems on a generic lattice. For states that are an equal superposition of elements of a group of spin flips acting on the fu…

Ground state entanglement and geometric entropy in the Kitaev's model
A. Hamma, R. Ionicioiu, P. Zanardi
We study the entanglement properties of the ground state in Kitaev's model. This is a two-dimensional spin system with a torus topology and nontrivial four-body interactions betwee…

Purity and State Fidelity of Quantum Channels via Hamiltonians
Paolo Zanardi, Daniel Lidar
We associate to every quantum channel acting on a Hilbert space a pair of Hamiltonian operators over the symmetric subspace of . The expe…
