英文摘要	When Alice and Bob share two pairs of quantum correlated states, Alice can remotely prepare quantum entanglement and quantum discord in Bob's side by measuring the parts in her side and telling Bob the measurement results by classical communication. For remote entanglement preparation, entanglement is necessary. We find that for some shared resources having the same amount of entanglement, when Bell measurement is used, the entanglement remotely prepared can be different, and more discord in the resources actually decreases the entanglement prepared. We also find that for some resources with more entanglement, the entanglement remotely prepared may be less. Therefore, we conclude that entanglement is a necessary resource but may not be the only resource responsible for the entanglement remotely prepared, and discord does not likely to assist this process. Also, for the preparation of discord, we find that some states with no entanglement could outperform entangled states.; National Science Fund for Distinguished Young Scholars of China [61225003]; National Natural Science Foundation of China [61101081]; National Hi-Tech Research and Development (863) Program; SCI(E); ARTICLE; luobin@bupt.edu.cn; hongguo@pku.edu.cn; 13-14; 1223-1232; 15
