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 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…
On the quantum, classical and total amount of correlations in a quantum state
Berry Groisman, Sandu Popescu, Andreas Winter
We give an operational definition of the quantum, classical and total amount of correlations in a bipartite quantum state. We argue that these quantities can be defined via the amo…
Lower bound on the number of Toffoli gates in a classical reversible circuit through quantum information concepts
Sandu Popescu, Berry Groisman, Serge Massar
The question of finding a lower bound on the number of Toffoli gates in a classical reversible circuit is addressed. A method based on quantum information concepts is proposed. The…
Frames of Reference and the Intrinsic Directional Information of a Particle With Spin
Daniel Collins, Sandu Popescu
"Information is physical", and here we consider the physical directional information of a particle with spin. We ask whether, in the presence of a classical frame of reference, suc…
