Probing Quantum Coherence with Free Electrons
Analysis
This paper presents a theoretical framework for using free electrons to probe the quantum-coherent dynamics of single quantum emitters. The significance lies in the potential for characterizing these dynamics with high temporal resolution, offering a new approach to study quantum materials and single emitters. The ability to observe coherent oscillations and spectral signatures of quantum coherence is a key advancement.
