We demonstrate distributed quantum sensing in field and show the unconditional violation (without post-selection) of shot-noise limit up to 0.916 dB with the averaged heralding efficiency of 73.88% for the field distance of 240 m.Authors: Si-Ran Zhao, Hefei National Laboratory for Physical Sciences at the Microscale and Department of Modern Physics, University of Science and Technology of China, Hefei 230026, China / Yu-Zhe Zhang, Hefei National Laboratory for Physical Sciences at the Microscale and Department of Modern Physics, University of Science and Technology of China, Hefei 230026, China / Wen-Zhao Liu, Hefei National Laboratory for Physical Sciences at the Microscale and Department of Modern Physics, University of Science and Technology of China, Hefei 230026, China / Jian-Yu Guan, Hefei National Laboratory for Physical Sciences at the Microscale and Department of Modern Physics, University of Science and Technology of China, Hefei 230026, China / Weijun Zhang, State Key Laboratory of Functional Materials for Informatics, Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, Shanghai 200050, P.
