Area laws and entanglement distillability of thermal states
Daniel Cavalcanti, Alessandro Ferraro, Artur Garcia-Saez +1
We study the entanglement distillability properties of thermal states of many-body systems. Following the ideas presented in [D.Cavalcanti et al., arxiv:0705.3762], we first discus…
Local temperature in quantum thermal states
A. Garcia-Saez, A. Ferraro, A. Acin
We consider blocks of quantum spins in a chain at thermal equilibrium, focusing on their properties from a thermodynamical perspective. Whereas in classical systems the temperature…
Thermal bound entanglement in macroscopic systems and area laws
A. Ferraro, D. Cavalcanti, A. Garcia-Saez +1
Does bound entanglement naturally appear in quantum many-body systems? We address this question by showing the existence of bound-entangled thermal states for harmonic oscillator s…
