Ghost Imaging with Free Electron-Photon Pairs
arXiv:2509.14950 · doi:10.1103/hqdr-795h
Abstract
Coincidence imaging, also known as ghost imaging, is a technique that exploits correlations between two particles to reconstruct information about a specimen. The particle that relays the spatial information about the object remains completely non-interacting, while the particle used to probe the object is not spatially resolved. While ghost imaging has been primarily implemented on photonic platforms, it becomes particularly intriguing when applied to particles with fundamentally different properties, such as massive, charged electrons and massless, neutral photons, especially considering the role of both particles as cornerstones of highly advanced microscopic platforms. In this work, we investigate coincidence imaging using electron-cathodoluminescence photon pairs generated within a transmission electron microscope. Utilizing a custom-built free-space cathodoluminescence setup, we demonstrate ghost imaging of complex patterns. We are able to obtain a spatial resolution down to 2 m, paving the way for adaptation of quantum-enhanced imaging techniques from photonic quantum optics to electron microscopy.
