The electron microscope as a quantum gate
Peter Schattschneider, Stefan Löffler
We propose to use the topological charge instead of the spin variable to span a two-dimensional Hilbert space for beam electrons in a transmission electron microscope (TEM). In thi…

Entanglement and Entropy in Electron-Electron Scattering
Peter Schattschneider, Stefan Löffler, Herbert Gollisch +1
Treating Coulomb scattering of two free electrons in a stationary approach, we explore the momentum and spin entanglement created by the interaction. We show that a particular disc…
