Feasibility of Quantum Computing with Electrons Trapped in a Paul Trap
Abstract
This project studies the feasibility of a novel architecture for quantum computing which uses 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 theoreti- cally and experimentally, and identify potential road blocks of using electrons for this novel quantum technology. To that end, we propose to trap electrons in Paul traps and demonstrate the fundamen- tal building blocks of a trapped-electron quantum computer. Building on the technology of generating AC-magnetic field gradients already developed for trapped ions, the spin degree- of-freedom of the electrons will be initialized, coherently controlled and measured. As com- pared 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 op- tical engineering challenges trapped ions face for building large scale quantum information processing devices.
