Integrated photonics facilitates control over fundamental light-matter interactions in manifold quantum systems. Extending these capabilities to electron beams [1] fosters free-electron quantum optics.
Here, we show the coupling of single electrons and photons at a high-Q integrated photonic microresonator [2]. Spontaneous scattering at empty resonator modes creates electron-photon pair states [3], enabling single-particle heralding schemes and noise-supressed mode imaging. This provides a pathway toward novel hybrid quantum technology with entangled electrons and photons, as well as the capability for quantum-enhanced electron imaging and Fock-state photon sources.
