Multiparty-Controlled Remote Preparation of Two-Particle State
Kui Hou, Jing Wang, Yuan Hao, Shi Shou-Hua · Communications in Theoretical Physics · 2009
We propose a scheme for multiparty-controlled remote preparation of the two-particle state by using two non-maximally Greenberger–Horne–Zeilinger states as quantum channel. Our scheme consists of one sender and n remote receivers. It will be shown that the sender can help either one of the n receivers to remotely preparation the original state with the appropriate probability, and the sender Alice's two-particle projective measurement and the controllers' single-particle product measurements are needed. We also obtained the probability of the successful remote state preparation.
