Single-Photon Fourier Transform
Zhen Yang, Zeng-Quan Yan, Li Wang +3
The extraction of information carried by light plays an increasingly important role in optical communication, imaging, and detection. However, the information can only be successfu…
Double-sphere enhanced optomechanical spectroscopy constrains symmetron dark energy
Jiawei Li, Ka-Di Zhu
Screened scalar fields such as the symmetron provide a viable description of dark energy yet their laboratory detection remains challenging. We propose an optomechanical scheme to…
Femtojoule-per-operation photonic computer for the subset sum problem
Tian-Yu Zhang, Xiao-Yun Xu, Wen-Hao Zhou +7
Energy-efficient computing is becoming increasingly important in the information era. However, electronic computers with von Neumann architecture can hardly meet the challenge due…
Constraining symmetron fields with a levitated optomechanical system
Jiawei Li, Ka-di Zhu
The symmetron, one of the light scalar fields introduced by dark energy theories, is thought to modify the gravitational force when it couples to matter. However, detecting the sym…
