A wide area quantum key distribution (QKD) network deployed on communication infrastructures provided by China Mobile Ltd. is demonstrated. Three cities and two metropolitan area QKD networks were linked up to form the Hefei-Chaohu-Wuhu wide area QKD network with over 150 kilometers coverage area, in which Hefei metropolitan area QKD network was a typical(More)
Measurement-device-independent quantum key distribution (MDI QKD) is a substantial step toward practical information-theoretic security for key sharing between remote legitimate users (Alice and Bob). As with other standard device-dependent quantum key distribution protocols, such as BB84, MDI QKD assumes that the reference frames have been shared between(More)
AIM To construct the eukaryotic expression vector of human spleen tyrosine kinase (Syk) and study the effect of Syk on MHC-I expression of human breast cancer cells. METHODS A CDS fragment of human syk was obtained by RT-PCR from human breast cancer cells MDA-MB-468 and then the fragment was cloned into the expression vector pcDNA3.1D/V5-His-TOPO. After(More)
