摘要：

Gaussian steering is used to characterize the intrinsic quantum correlation of Gaussian states under Gaussian measurement. Here we study the generation of one-way Gaussian steering and the conversion of one-way Gaussian steering. It is found that one-way Gaussian steering could be generated by using Gaussian channels, either the Gaussian lossy channel or the Gaussian amplification channel. Exploiting the one-way Gaussian steering in a two-partite quantum system consists of two subsystems marked with A and B, one-way Gaussian steering (steering from A to B) can be converted to the other one-way Gaussian steering (steering from B to A) using linear optics, and vice versa.
