Developing a Quantum Electron Microscope

POSTER

Abstract

We develop a new electron microscope based on the interaction-free measurement principle [1,2]. Such a Quantum Electron Microscope (QEM) [3] may enable imaging of biological samples with radiation doses so small that they are non-lethal. The realization of the QEM will require precise control over the quantum motion of free electrons. On this poster, we discuss our approach to build a QEM including the realization of an electron resonator and an electron amplitude beam-splitter. On top of the QEM application, these developments will advance the electron analogue to photon quantum optics.[1] A. C. Elitzur and L. Vaidman, Found. Phys. 23, 987 (1993)[2] P. Kwiat, H.
