Detection of Single Electrons on Superfluid Helium

Abstract

The goal of this project is to be able to detect single electrons for quantum computing applications in which electron-spin is used as the qubit. We will use a Colpitts oscillator for cryogenic capacitance measurement. The work performed thus far and the results that are presented are intended to provide a proof of concept for this system by using a Colpitts oscillator measurement scheme to detect a liquid helium level based on changes in capacitance in the tank circuit.
