Physical Review Letters 2004年 第14期93卷 140407-140407页
作者: Jing-Ling Chen Chunfeng Wu L. C. Kwek C. H. Oh Department of Physics National University of Singapore 2 Science Drive 3 Singapore 117542 Institute of Applied Physics and Computational Mathematics P.O. Box 8009 (26) 100088 Beijing China Nanyang Technological University National Institute of Education 1 Nanyang Walk Singapore 637616
We present a theorem that all generalized Greenberger-Horne-Zeilinger states of a three-qubit system violate a Bell inequality in terms of probabilities. All pure entangled states of a three-qubit system are shown to ... 详细信息
