Distillable entanglement and area laws in spin and harmonic-oscillator systems
D. Cavalcanti, A. Ferraro, A. Garcia-Saez +1
We address the presence of non-distillable (bound) entanglement in natural many-body systems. In particular, we consider standard harmonic and spin-1/2 chains, at thermal equilibri…
Joint measurements on qubits and cloning of observables
Alessandro Ferraro, Matteo G A Paris
Cloning of observables, unlike standard cloning of states, aims at copying the information encoded in the statistics of a class of observables rather then on quantum states themsel…
Monogamy and ground-state entanglement in highly connected systems
Alessandro Ferraro, Artur Garcia-Saez, Antonio Acin
We consider the ground-state entanglement in highly connected many-body systems, consisting of harmonic oscillators and spin-1/2 systems. Varying their degree of connectivity, we i…
