A team led by Guo Guangcan from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) explored non-Markovian behaviors of Einstein-Podolsky-Rosen (EPR) steering in quantum processes and revealed the whole evolution of EPR steering in quantum open systems. This work was published in Physical Review Letters.

EPR steering describes a quantum nonlocal phenomenon in which one party can nonlocally affect the other's state through local measurements, which represents a concept of quantum non-locality between entanglement and Bell nonlocality. Its distinctive directional property allows one-way EPR steering that can provide resources for quantum information tasks.
