      "summary_nl": "When electrons travel across a nano-scale landscape, they interact strongly with their own image, reflected in the substrate. As a result, they can emit radiation, known as Smith Purcell emission. This research seeks to understand the quantum-coherent character of this radiation. The quantum coherence of the generated light will be studied by preparing Bell states that are analysed with an interferometer. Others have investigated the quantum-coherent nature of the interaction between free electrons and classical light in the vicinity of nanoscale objects and surfaces. However, the quantum-coherence of photon generation that is stimulated by only a single electron and is mediated by nanostructured surfaces has not been explored experimentally as will be done in this proposal.\n\nGiven the kinetic energy of each electron is much greater than the photon energy, large numbers of photons might be generated per electron. The use of single-photon and single-electron detectors opens up avenues for electron-heralded photon sources, and vice versa. The findings of this work could impact applications in quantum computing, communication, and metrology by providing efficient, low-noise, and highly-tuneable single-electron, single-photon, and entangled large-photon-number sources.",
