The foundations of statistical mechanics from entanglement: Individual states vs. averages
Sandu Popescu, Anthony J. Short, Andreas Winter
We consider an alternative approach to the foundations of statistical mechanics, in which subjective randomness, ensemble-averaging or time-averaging are not required. Instead, the…
Entanglement swapping for generalized non-local correlations
Tony Short, Sandu Popescu, Nicolas Gisin
We consider an analogue of entanglement-swapping for a set of black boxes with the most general non-local correlations consistent with relativity (including correlations which are…
On the entanglement concentration of three-partite states
Berry Groisman, Noah Linden, Sandu Popescu
We investigate the concentration of multi-party entanglement by focusing on simple family of three-partite pure states, superpositions of Greenberger-Horne-Zeilinger states and sin…
The Entanglement of Superpositions
Noah Linden, Sandu Popescu, John A. Smolin
Given a bipartite quantum state (in arbitrary dimension) and a decomposition of it as a superposition of two others, we find bounds on the entanglement of the superposition state i…
The physics of no-bit-commitment : Generalized quantum non-locality versus oblivious transfer
Tony Short, Nicolas Gisin, Sandu Popescu
We show here that the recent work of Wolf and Wullschleger (quant-ph/0502030) on oblivious transfer apparently opens the possibility that non-local correlations which are stronger…
