Ghost Imaging with Free Electron-Photon Pairs
Sergei Bogdanov, Alexander Preimesberger, Harsh Mishra +11
Coincidence imaging, also known as ghost imaging, is a technique that exploits correlations between two particles to reconstruct information about a specimen. The particle that rel…
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…
Electron-Enabled Nanoparticle Diffraction
Stefan Nimmrichter, Dennis Rätzel, Isobel C. Bicket +2
We propose a scheme for generating high-mass quantum superposition states of an optically pre-cooled, levitated nanoparticle through electron diffraction at its sub-nanometer cryst…
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…
