Phase-Locked Photon-Electron Interactions for Ultrafast Spectroscopy beyond T2

Introduction

Based on my groundbreaking advancements in realizing internal radiation sources inside electron microscopes, generating ultrashort and coherent electromagnetic radiations in interaction with electron beams, I propose to develop a platform for ultrafast and phase-locked electron-beam spectroscopy of solid-state-based quantum networks, beyond the dephasing time T2.

Key Elements

My platform relies on the following key elements:

1. Shaping electron wavepackets with light.
2. Implementing three-dimensional electron-driven photon sources.
3. Employing correlative measurements to unravel the quantum statistics of photons evolving in solid-state-based photonic systems and quantum networks.

This scenario enables an outstanding temporal resolution and an unprecedented degree of mutual coherence between the radiation sources and the near-field of the electron wavepacket itself.

Objectives

By combining these capabilities, I aim to:

• Map the excitation/emission paths.
• Investigate quasi-particle interactions.
• Analyze charge and energy transfer dynamics.
• Explore quantum jump and revival processes at the attosecond timescale and nanometer spatial resolution.

Impact

UltraSpecT opens new horizons in quantum-sensitive measurements, leveraging novel technological advancements in electron microscopes to explore the frontiers of quantum science. It aims to investigate decoherence dynamics beyond T2 using electron microscopes, enabling the exploration and manipulation of photon dynamics in individual single-photon emitters coupled to or embedded in quantum networks.

Interdisciplinary Approach

UltraSpecT's ambitious goals span a highly interdisciplinary field, combining quantum optics with electron microscopy. My team and I will address the ambitious aspects of UltraSpecT by applying our extensive knowledge in both theoretical and experimental aspects of electron – light – matter interactions.

Risk Mitigation

I will further implement a risk mitigation plan that includes employing a variety of methods to realize our required radiation sources and beam shaping strategies.
