Elastic Quantum Coupling Between Free Electrons and Photons
Dingguo Zheng, Ofer Kfir
The quantum coupling between free-electrons and photons enables applying quantum optics techniques in electron microscopy. Here, we formulate the elastic electron-photon quantum co…
Quantum state heralding using photonic integrated circuits with free electrons
Guanhao Huang, Nils J. Engelsen, Ofer Kfir +2
Recently, integrated photonic circuits have brought new capabilities to electron microscopy and been used to demonstrate efficient electron phase modulation and electron-photon cor…
Optical coherence transfer mediated by free electrons
Ofer Kfir, Valerio Di Giulio, F. Javier García de Abajo +1
We investigate theoretically the quantum-coherence properties of the cathodoluminescence (CL) emission produced by a temporally modulated electron beam. Specifically, we consider t…
Entanglements of electrons and cavity-photons in the strong coupling regime
Ofer Kfir
This work sets a road-map towards an experimental realization of strong coupling between free-electrons and photons, and analytically explores entanglement phenomena that emerge in…
