Bipartite non-locality beyond Bell inequalities by means of multivariable correlations
Bruno Leggio, Bruno Bellomo, Romain Azaïs +2
We give a set of necessary conditions for locality in bipartite systems, which include and generalize known Bell's inequalities. Each condition corresponds to a specific order of t…
Bounds on mixed state entanglement
Bruno Leggio, Anna Napoli, Hiromichi Nakazato +1
In the general framework of mixed states, we derive an explicit bound for bipartite NPT entanglement based on the mixedness characterization of the physical system. The…
Otto engine beyond its standard quantum limit
Bruno Leggio, Mauro Antezza
We propose a quantum Otto cycle based on the properties of a two-level system in a realistic out-of-thermal-equilibrium electromagnetic field acting as its sole reservoir. This ste…
Heat Capacity and Entanglement Measure in a simple two-qubit model
B. Leggio, A. Napoli, H. Nakazato +1
A simple two-qubit model showing Quantum Phase Transitions as a consequence of ground state level crossings is studied in detail. Using the Concurrence of the system as an entangle…
