During the quantum optics and quantum information session, Professor Yu-Bo Sheng presented a report, titled “Theoretical and Experimental Advances in Quantum Entanglement Purification”. During the report, as the deputy editor of the AAPPS Bulletin (AB), Professor Sheng recommended the AB to the audience. He noted that the impact factor of AB is 5.9 and that AB hopes to benchmark against Nature Physics in the future. AB is striving to become the most prestigious journal in the Asia–Pacific region.
