Probing Quantum Coherence with Free Electrons
Analysis
Key Takeaways
- •Develops a quantum theory for free electron interaction with quantum emitters.
- •Predicts that free electrons can induce coherent oscillations in emitter populations.
- •Identifies spectral signatures of quantum coherence in the electron energy spectrum.
- •Suggests a new method for characterizing quantum-coherent dynamics of individual quantum emitters.
“The electron energy spectrum exhibits a clear signature of the quantum coherence and sensitivity to the transition frequency of the emitter.”
