Coupling free electrons to a trapped-ion quantum computer
Elias Pescoller, Santiago Beltrán-Romero, Sebastian Egginger +10
Freely propagating electrons may serve as quantum probes that can become coherently correlated with other quantum systems, offering access to advanced metrological resources. We pr…
Quantum Metrology of Spin Sensing with Free Space Electrons
Santiago Beltrán-Romero, Michael Gaida, Philipp Haslinger +2
Recent advances in transmission electron microscopy (TEM) have opened the path toward spin resonance spectroscopy with single-spin sensitivity. To assess this potential, we investi…
Coherent Driving of a Quantum System with Modulated Free-Space Electrons
Matthias Kolb, Thomas Spielauer, Thomas Weigner +3
Control of quantum systems typically relies on the interaction with electromagnetic radiation. In this study, we experimentally show that the electromagnetic near-field of a spatia…
The Sound of Entanglement
Enar de Dios Rodríguez, Philipp Haslinger, Johannes Kofler +5
The advent of quantum physics has revolutionized our understanding of the universe, replacing the deterministic framework of classical physics with a paradigm dominated by intrinsi…
Experimental Verification of Electron-Photon Entanglement
Alexander Preimesberger, Sergei Bogdanov, Isobel C. Bicket +2
Entanglement, a key resource of emerging quantum technologies, describes correlations between particles that defy classical physics. It has been studied extensively on various plat…
Sensing Spin Systems with a Transmission Electron Microscope
Antonín Jaroš, Michael S. Seifner, Johann Toyfl +3
We present a novel method that combines spin resonance spectroscopy with transmission electron microscopy (TEM), enabling localized in-situ detection of microwave (MW)-driven spin…
