A Proof of the Security of Quantum Key Distribution
Eli Biham, Michel Boyer, P. Oscar Boykin +2
We prove the security of theoretical quantum key distribution against the most general attacks which can be performed on the channel, by an eavesdropper who has unlimited computati…
Valence-Bond-Solid state entanglement in a 2-D Cayley tree
Heng Fan, Vladimir Korepin, Vwani Roychowdhury
The Valence-Bond-Solid (VBS) states are in general ground states for certain gapped models. We consider the entanglement of VBS states on a two-dimensional Cayley tree. We show tha…
Exact Entanglement Cost of Multi-Qubit Bound Entangled States
Somshubhro Bandyopadhyay, Vwani P. Roychowdhury
We report the exact entanglement cost of a class of multiqubit bound entangled states, computed in the context of a universal model for multipartite state preparation. The exact am…
