Researchers shed light on memory effects in multi-step evolution of open quantum system

In a study published in Physical Review Letters, academician Guo Guangcan’s team from University of Science and Technology of China of the Chinese Academy of Sciences made progress in the open quantum system research. This team, collaborating with Austrian theoretical physicist Philip Taranto, demonstrated the non-Markovianity in the multi-step evolution of the open quantum system, and proved the measurement-dependent property of quantum memory effects.
