In contrast, free-electron<\/em> systems enable fundamentally different physical phenomena, as their energy distribution is continuous and not discrete, allowing for tunable transitions and selection rules.<\/p>\n\n\n\n Recent theoretical and experimental breakthroughs involving quantum interactions of free electrons spawned an exciting new field: free-electron quantum optics<\/em>. We developed a platform for exploring free-electron quantum optics at the nanoscale, based on a laser-driven transmission electron microscope. We used this platform to demonstrate the first coherent interaction of a free electron with a photonic cavity and with the quantum statistics of photons.<\/p>\n\n\n\n These capabilities open new paths toward using free electrons as carriers of quantum information. Free electrons emerge as quantum optical sources for desired photonics states used in fault-tolerant quantum computation and communication such as Schrodinger cat states and Gottesman-Kitaev-Preskill (GKP) states.<\/p>\n\n\n\n Concepts of quantum optics with free electrons also promote new modalities in electron microscopy. We demonstrated the first instance of coherent amplification<\/em> in electron microscopy. Our vision is to develop a microscope that can image coherence<\/em>, going beyond conventional imaging of matter to also image the coherent quantum state of matter and probe quantum correlations between individual quantum systems.<\/p>\n\n\n\n <\/p>\n\n\n\n Monday, 04 December 2023<\/strong><\/p>\n\n\n\n at Lise Meitner Lecture Hall at Universit\u00e4t Wien 17:00<\/strong> VCQ Student talk by Alexander Preimesberger<\/strong><\/p>\n\n\n\n Investigating Correlated Electron-Photon Pairs in a Transmission Electron Microscope<\/strong><\/p>\n\n\n\n 17:15<\/strong> VCQ Colloquium talk by Ido Kaminer<\/strong><\/p>\n\n\n\n
