relative entropy of entanglement of two-qubit 'X' states
收藏 引用
Chinese Physics B 2010年 第11期19卷 84-89页
作者: 黄接辉 刘念华 刘江涛 于天宝 何弦 Department of Physics Nanchang University
Two closest single-qubit states could be diagonalised by the same unitary matrix, which helps to find the relative entropy of entanglement of a two-qubit 'X' state. We formulate two binary equations for the relative... 详细信息

relative entropy of entanglement of a Kind of Two-Qubit Entangled States
收藏 引用
Chinese Physics Letters 2005年 第11期22卷 2755-2758页
作者: 陈小余 孟利民 蒋丽珍 李向军 School of Science China Institute of Metrology Hangzhou 310018 College of Information Engineering Zhejiang University of Technology Hangzhou 310032
We strictly prove that some block diagonalizable two-qubit entangled state with six non-zero elements reaches its quantum relative entropy entanglement by a separable state having the same matrix structure. The entang... 详细信息

Revised Geometric Measure of entanglement for Multipartite and Continuous Variable Systems
收藏 引用
Communications in Theoretical Physics 2009年 第4期51卷 613-620页
作者: CAO Ya WANG An-Min Department of Physics Xuzhou Normal University Xuzhou 221116 China Department of Modern Physics University of Science and Technology of China Hefei 230026 China
Based on the revised geometric measure of entanglement (RGME) proposed by us [J. Phys. A: Math. Theor. 40 (2007) 3507], we obtain the RGME of multipartite state including three-qubit GHZ state, W state, and the g... 详细信息
