  bibo_abstract:
  - 'A central challenge in the emerging field of free-electron quantum optics is
    to achieve strong quantum interaction and single-photon nonlinearity between a
    flying free electron and a photonic mode. Existing schemes are intrinsically limited
    by electron diffraction, which puts an upper bound on the interaction length and,
    therefore, on the strength of quantum coupling and nonlinearity. Here, we propose
    “free-electron fibers”: effectively one-dimensional photonic systems where free
    electrons copropagate with two guided modes. The first mode applies a ponderomotive
    trap to the free electron, removing the limitations due to electron diffraction.
    The second mode strongly couples to the guided free electron with an enhanced
    coupling that is orders of magnitude larger than previous designs. The extended
    interaction lengths enabled by our scheme allow for strong single-photon nonlinearities
    mediated by free electrons. We predict novel quantum effects in our system such
    as deterministic single-photon emission and nonlinear multimode dynamics. Our
    proposal paves the way toward the realization of heralded macroscopic nonclassical
    light generation, deterministic single-photon sources, and quantum gates controlled
    by free-electron–photon interactions.@eng'
