Efficient entanglement concentration for arbitrary less-entangled NOON state assisted by single photons
收藏 引用
Chinese Physics B 2016年 第2期25卷 98-105页
作者: 周澜 盛宇波 College of Mathematics and Physics Nanjing University of Posts and Telecommunications Key Laboratory of Broadband Wireless Communication and Sensor Network Technology Ministry of EducationNanjing University of Posts and Telecommunications Institute of Signal Processing Transmission Nanjing University of Posts and Telecommunications
We put forward two efficient entanglement concentration protocols (ECPs) for arbitrary less-entangled NOON state. Both ECPs only require one pair of less-entangled NOON state and an auxiliary photon. In the first EC... 详细信息
