Research team realizes quantum-enhanced microwave ranging

A study published in Nature Communications highlights the progress made in practical quantum sensing by a team led by academician Guo Guangcan and Prof. Sun Fangwen from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS). The team utilized micro and nano quantum sensing, coupled with local electromagnetic field enhancement at deep sub-wavelength scales, to study the detection of microwave signals and wireless ranging, achieving a positioning accuracy of 10-4 wavelengths.
