Quantum information can be negative
Michal Horodecki, Jonathan Oppenheim, Andreas Winter
Given an unknown quantum state distributed over two systems, we determine how much quantum communication is needed to transfer the full state to one system. This communication meas…
Characterization of combinatorially independent permutation separability criteria
Pawel Wocjan, Michal Horodecki
The so-called permutation separability criteria are simple operational conditions that are necessary for separability of mixed states of multipartite systems: (1) permute the indic…
Simplifying monotonicity conditions for entanglement measures
Michal Horodecki
We show that for a convex function the following, rather modest conditions, are equivalent to monotonicity under local operations and classical communication. The conditions are: 1…
The Universal Composable Security of Quantum Key Distribution
M. Ben-Or, Michal Horodecki, D. W. Leung +2
The existing unconditional security definitions of quantum key distribution (QKD) do not apply to joint attacks over QKD and the subsequent use of the resulting key. In this paper,…
