Simulating Microwave-Controlled Spin Imaging with Free-Space Electrons
Santiago Beltrán-Romero, Stefan Löffler, Dennis Rätzel +1
Coherent spin resonance techniques, such as nuclear and electron spin resonance spectroscopy, have revolutionized non-invasive imaging by providing spectrally resolved information…
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…
