DESCRIPTION:Speakers: 利剑 张 (南京大学)\n摘要：Quantum metrolog
 y\, leveraging quantum resources and manipulation techniques\, offers meas
 urement capabilities that surpass the limits of its classical counterpart.
  It holds the promise of driving key breakthroughs in both fundamental sci
 entific research and practical engineering applications. Consequently\, it
  has emerged as one of the three primary pillars of quantum information te
 chnology. Over the past two decades\, this field has witnessed remarkable 
 progress\, with successful implementations across various physical systems
 \, including photons\, atoms\, ions\, nitrogen-vacancy (NV) centers\, and 
 nuclear magnetic resonance (NMR). Among these\, photonic systems serve as 
 a crucial platform for quantum precision measurement due to their inherent
  advantages\, such as long coherence time and strong resistance to environ
 mental disturbance. Furthermore\, the rich and easily manipulable degrees 
 of freedom of photons make them highly adaptable to a wide range of precis
 ion measurement scenarios. The further advancement of photonic quantum met
 rology relies on the development of technologies for preparing and detecti
 ng quantum probe states\, the enhancement of system robustness (i.e.\, imp
 roved noise tolerance)\, and the exploration of novel measurement methodol
 ogies tailored for increasingly complex tasks. This presentation will brie
 fly introduce the fundamental principles of photonic quantum metrology\, f
 ollowed by an overview of our recent research progress in quantum interfer
 ometry\, weak measurement\, and multi-parameter quantum precision measurem

 ing University\, China. He then moved to University of Oxford in UK and re
 ceived his D.Phil degree in Atomic and Laser Physics. After the graduation
  he stayed at University of Oxford as a postdoctoral research assistant. I
 n 2011 he joined the Max-Planck Institute for Structures and Dynamics of M
 atter in Hamburg as a Humboldt research fellow. Since 2013 he has been a p
 rofessor at Nanjing University in China. His research interests include th
 e generation\, manipulation and detection of non-classical states of light
 \, and their applications in communication\, metrology\, computation and s
 imulation. He has published over 60 papers in international refereed journ
 als including Science\, Nature Photonics\, Nature Materials\, Physical Rev
 iew Letters etc.\nhttps://indico.ihep.ac.cn/event/28885/
