Quantum Enhanced Microscopy

Our group is collaborating with several UTEM groups on the realization of quantum experiments involving electron-light interactions.

UTEM enables the creation of electron beam pulses synchronized with the light-based pump of the sample.

However, we aim to follow a different route.

We are focusing on coincidence experiments using a continuous wave approach.

Currently, we are working on the theory, and in the future, we plan to conduct experiments involving coincidence detection of electrons and light.

The goal is to demonstrate and exploit electron-light entanglement through the use of light resonators placed near the electron beam. This approach will allow us to explore phenomena such as Bell inequalities, Ramsey holography, and more.

In the scheme above, we illustrate the relationship between standard UTEM experiments and concepts like coincidence and ghost imaging.

At the same time, we have initiated efforts to improve the idea of spectroscopy for inelastic scattering in electron microscopy. This can be achieved through interference or inversion methods, such as inelastic ptychography.

We are actively working on the concept that quantum tomography of inelastic scattering is the most informative approach to understanding the details of scattering, particularly through its phasing and coherence.
