Interference Alignment at Finite SNR for Time-Invariant Chan...

IEEE Information Theory Workshop (ITW)
作者: Ordentlich, Or Erez, Uri Tel Aviv Univ Dept Elect Engn Syst IL-69978 Ramat Aviv Israel
A time-invariant (constant channel gains) K-user interference channel is considered, where all interference (cross) channel gains are integers. For such channels, previous results demonstrate that the number of degree... 详细信息

The Collection Channel In a Wireless Sensor Network
The Collection Channel In a Wireless Sensor Network

IEEE Information Theory Workshop (ITW)
作者: Larish, Bryan Riley, George Georgia Inst Technol Sch Elect & Comp Engn Atlanta GA 30332 USA
We define the collection channel in a Wireless Sensor Network (WSN) and show how this collection channel can be used in the proofs of new types of coding theorems for WSNs. These coding theorems differ from traditiona... 详细信息

IEEE International Symposium on Information Theory (ISIT)
作者: Rangi, Anshuka Franceschetti, Massimo Univ Calif San Diego San Diego CA 92103 USA
The delta-mutual information between uncertain variables is introduced as a generalization of Nair's non-stochastic information functional. Several properties of this new quantity are illustrated, and used to prov... 详细信息

Entanglement of assistance and multipartite state distillation
收藏 引用
Physical Review A 2005年 第5期72卷 052317-052317页
作者: John A. Smolin Frank Verstraete Andreas Winter IBM T. J. Watson Research Center Yorktown Heights New York 10598 USA Institute for Quantum Information Caltech 107-81 Pasadena California 91125 USA Max-Planck-Institut für Quantenoptik Hans-Kopfermann-Str.1 85748 Garching Germany Department of Mathematics University of Bristol University Walk Bristol BS8 1TW United Kingdom
We find that the asymptotic entanglement of assistance of a general bipartite mixed state is equal to the smaller of its two local entropies. Our protocol gives rise to the asymptotically optimal Einstein-Podolsky-Ros... 详细信息

Universal quantum data compression via nondestructive tomography

Physical Review A 2006年 第3期73卷 032336-032336页
作者: Charles H. Bennett Aram W. Harrow Seth Lloyd IBM T. J. Watson Research Center P. O. Box 218 Yorktown Heights New York 10598 USA Department of Computer Science University of Bristol Bristol BS8 1UB United Kingdom Department of Mechanical Engineering MIT 77 Massachusetts Avenue Cambridge Massachusetts 02139 USA
Quantum-state tomography—the practice of estimating a quantum state by performing measurements on it—is useful in a variety of contexts. We introduce “gentle tomography” as a version of tomography that preserves t... 详细信息

Quantum, classical, and total amount of correlations in a quantum state
收藏 引用
Physical Review A 2005年 第3期72卷 032317-032317页
作者: Berry Groisman Sandu Popescu Andreas Winter H. H. Wills Physics Laboratory University of Bristol Tyndall Avenue Bristol BS8 1TL United Kingdom Hewlett-Packard Laboratories Stoke Gifford Bristol BS12 6QZ United Kingdom Department of Mathematics University of Bristol Bristol BS8 1TW United Kingdom
We give an operational definition of the quantum, classical, and total amounts of correlations in a bipartite quantum state. We argue that these quantities can be defined via the amount of work (noise) that is require... 详细信息

Reply to "Comment on 'Source coding with Tsallis entropy'"

ELECTRONICS LETTERS 2011年 第10期47卷 598-598页
作者: Chapeau-Blondeau, F. Delahaies, A. Rousseau, D. Univ Angers LISA F-49000 Angers France
The authors of [1] were unaware of this one sentence in [2] (page 3237): 'Since the Renyi and Tsallis entropy are related by a simple monotone transformation, inequalities similar to (8) and (20) exist with Tsalli... 详细信息
