Einstein-Podolsky-Rosen (EPR) steering shows an intermediate type of quantum nonlocality which is distinct from both quantum entanglement and Bell’s nonlocality, especially, one-way EPR steering has a significant influence on the secure quantum secret sharing. A scheme to effectively change the characteristic of EPR steering, which is implemented by adding noise to one part of an EPR state, is presented. With the introduction of the noise, the relationships between the steering parameters and the reflectivity of variable beam splitter are analyzed, and the change process of the EPR steering direction from two way to one way is investigated. This study is of great importance in the asymmetric quantum nonlocality control and the quantum control in the process of quantum information transmission.
