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…
A new inequality for the von Neumann entropy
Noah Linden, Andreas Winter
Strong subadditivity of von Neumann entropy, proved in 1973 by Lieb and Ruskai, is a cornerstone of quantum coding theory. All other known inequalities for entropies of quantum sys…
The Propagation of Quantum Information Through a Spin System
Tobias J. Osborne, Noah Linden
It has been recently suggested that the dynamics of a quantum spin system may provide a natural mechanism for transporting quantum information. We show that one dimensional rings o…
High order correlations of generic pure states of finite-dimensional quantum systems are determined by lower order correlations
N. Linden, W. K. Wootters
We show that almost every pure state of multi-party quantum systems (each of whose local Hilbert space has the same dimension) is completely determined by the state's reduced densi…
The power of reduced quantum states
N. Linden, S. Popescu, W. K. Wootters
In a system of n quantum particles, we define a measure of the degree of irreducible n-way correlation, by which we mean the correlation that cannot be accounted for by looking at…
Reversibility of local transformations of multiparticle entanglement
N. Linden, S. Popescu, B. Schumacher +1
We consider the transformation of multisystem entangled states by local quantum operations and classical communication. We show that, for any reversible transformation, the relativ…
