Experimental steps towards quantum information processing with trapped electrons
Abstract
This project aims at further steps towards establishing a novel architecture for quantum computing using trapped electrons as carriers of quantum information. In comparison to current state-of-the-art technologies, electrons have the potential of storing quantum information for longer times than solid-state systems and allow for reducing the technological overhead of atomic systems. It is the aim of this project to analyse these promising possibilities, both experimentally and theoretically, and to take the fi rst steps towards implement this novel quantum technology. To that end, we propose to trap electrons in a miniature cryogenic Paul trap reaching secular frequencies of 2 GHz and demonstrate the fundamental building blocks of a trapped electron quantum computer, such as cooling and detection. Building on the technology of generating AC-magnetic fi eld gradients already developed for trapped ions, the spin degree-of-freedom of the electrons will be initialized, coherently controlled and measured. As compared to trapped ions, the light mass of the electrons will increase the speed of operations considerably. In addition, radio-frequency and microwave radiation will be used to initialize, compute with, and read-out the quantum register. This removes the need to master the optical engineering challenges trapped ions face for building large scale quantum information processing devices.
