Recently,optoelectronic informationThe college is led by Professor Qiu QiOptical communications and photonicsThe research team published a paper titled 'Comment on' Uncertainty Relation for Photons' in Physical Review Letters, co authored by Wang Zhiyong, Xiong Caidong, and Qiu Qi.

nanophotonicsOne important topic in the study is related to quantum manipulation of microscopic particles at the nanoscale (the 2012 Nobel Prize in Physics involved quantum manipulation of microscopic particles), therefore research is neededphotonThe relationship between local features and positional momentum uncertainty in three-dimensional space has important theoretical interest and potential application value. Due to the zero rest mass of photons, there is no position operator in the usual quantum mechanical sense, which makes the problem complex and difficult. The author of the paper points out the shortcomings in previous theories based on previous research and proposes their own alternative theoretical solutions.

The main author, Associate Professor Wang Zhiyong, has won the National Doctoral Dissertation Nomination Award (supervised by Professor Xiong Caidong). In the past five years, he has published 10 SCI papers in academic journals, including 1 Physical Review Letter (IF: 7.37); Physics Letters B（IF：5.083）， 2 articles; Annals of Physics （IF：3.253）， 1 article; Physical Review A （IF：2.878）， 6 articles.

It is reported that Professor Qiu Qi's team emphasizes both basic theoretical research and applied technology research. Under the leadership of Professor Qiu Qi, the team has a down-to-earth and diligent work style, with a rigorous and lively academic atmosphere. The team isFiber optic delay lineResearch in the field of technology is at a domestic level; The research on homodyne coherent optical communication has begun to take shape.
