Electron beams offer a unique additial element in the quantum photonic Lego. The control over the longitudinal and transverse properties of electron beams has recently experienced an impressive boost because of the combination of new advances in electron microscope instrumentation, in particular with the use of ultrafast light pulses, and the ability to synthesize femtosecond electron wave packets.
In this talk, we will overview key concepts describing the associated interactions between free electrons, light, and photonic nanostructures, making emphasis on quantum aspects and exploring several exciting challenges and emerging opportunities. We will further discuss potential applications in noninvasive spectroscopy and microscopy, the possibility of sampling the nonlinear optical response at the nanoscale, the manipulation of the density matrices associated with free electrons and optical modes in a specimen, optical modulation of electron beams, and improved schemes for electron-driven light emission over a wide range of photon energies.
