Recently, Professor Kihwan Kim, assistant researchers Pengfei Wang and Jing-Ning Zhang from BAQIS, in cooperation with Tsinghua University, University de Seville and Southern University of Science and Technology, have experimentally demonstrated the first loophole-free quantum contextuality test. The work titled with "Significant loophole-free test of Kochen-Specker contextuality using two species of atomic ions" was published in Science Advances on February 9th.

In the study “Coherent phase transfer for real-world twin-field quantum key distribution”, published in Nature Communications, the Italian INRiM team demonstrated experimentally that coherent laser interferometry considerably improves the performances of long-distance quantum communication in real-world networks. BAQIS Chief Scientist Zhiliang Yuan contributed to the design of the experimental setup.

Dr. Yan Liu, BAQIS Assistant Researcher from Atomic Ensemble Precision Measurement Group, and his collaborators from Germany proposed and realized calibration of magnetic force microscopy with a single NV center. The results have been published on Physical Review B recently.

Recently, a research team led by Jian-Hao Chen, who is Principle Investigator of the in-situ quantum transport group in BAQIS, demonstrated electrically switchable magnon valves based on the highly tunable two-dimensional magnons in van der Waals antiferromagnetic insulator MnPS3.
