Entanglement Distribution in Pure-State Quantum Networks
S. Perseguers, J. Wehr, A. Acin +2
We investigate entanglement distribution in pure-state quantum networks. We consider the case when non-maximally entangled two-qubit pure states are shared by neighboring nodes of…
Frustration, Area Law, and Interference in Quantum Spin Models
Aditi Sen De, Ujjwal Sen, Jacek Dziarmaga +2
We study frustrated quantum systems from a quantum information perspective. Within this approach, we find that highly frustrated systems do not follow any general ''area law'' of b…
Entanglement of positive definite functions on compact groups
J. K. Korbicz, J. Wehr, M. Lewenstein
We define and study entanglement of continuous positive definite functions on products of compact groups. We formulate and prove an infinite-dimensional analog of Horodecki Theorem…
Statistical-mechanical description of quantum entanglement
J. K. Korbicz, F. Hulpke, A. Osterloh +1
We present a description of finite dimensional quantum entanglement, based on a study of the space of all convex decompositions of a given density matrix. On this space we construc…
Separability, entanglement and full families of commuting normal matrices
Jan Samsonowicz, Marek Kus, Maciej Lewenstein
We reduce the question whether a given quantum mixed state is separable or entangled to the problem of existence of a certain full family of commuting normal matrices whose matrix…
