对称多量子比特系统中的成对纠缠

Pairwise entanglement in symmetric multi-qubit systems

Xiaoguang Wang, Klaus Molmer

摘要:

同时,一对粒子之间的纠缠的定量测量,确定的情况下,该对是从N个二能级系统的对称态提取。例子给出了纯态和混合态的N粒子系统,并从两个合奏与相关的集体自旋对提取。

英文摘要:

The concurrence, a quantitative measure of the entanglement between a pair of particles, is determined for the case where the pair is extracted from a symmetric state of N two-level systems. Examples are given for both pure and mixed states of the N-particle system, and for a pair extracted from two ensembles with correlated collective spins.
