NewsUpper Bound for the Quantum Coupling between Free Electrons and Photons, published in PRL
The fundamental limit of free-electron—light coupling is an important question relevant to frontier studies to reach the strong coupling regime, which is crucial for applications such as free-electron based photon sources, quantum sensing and quantum computing using free electrons. This study rigorously establishes the fundamental upper bound of free-electron—photon coupling. The upper bound has a […]The fundamental limit of free-electron—light coupling is an important question relevant to frontier studies to reach the strong coupling regime, which is crucial for applications such as free-electron based photon sources, quantum sensing and quantum computing using free electrons.
