Abstract

The “Quantum Measurement Problem” is an unsolved mystery that stops us from bridging the gap between the microscopic and the macroscopic world. To solve this mystery, microscopic objects, electrons, are placed close to a macroscopic everyday world object, a wall. From a practical perspective, it has been proposed that the interaction between electrons and walls limits how small an object an electron microscope can see. If the effects of this interaction can be overcome, we may improve electron microscopes. A second objective of this project is to look at the microscopic, quantum properties of a group of electrons close to each other. Now we have changed the interaction between an electron and a wall to the interaction between electrons. It is predicted that these quantum properties can be used to further improve electron microscopes. The research project provides training for graduate students, undergraduate students and high school students in quantum science, which is an area of national need. The technologies we develop, which include visualization of our work with Augmented Reality headsets, are aimed to strengthen the national economy. The work is done by using electron diffraction from a nanofabricated grating to make a coherent electron quantum wave. By placing a gold coated wall close to the electron wave, we not only decohere the wave, but Caldeira and Leggett also predict an electron energy loss. If we can find the decoherence-energy loss relation, we have demons
