The development of an experimental quantum information processor based on trapped ions

Lead Research Organisation: University of Oxford
Department Name: Oxford Physics

Abstract

Brief description of the context of the research including potential impact;

The context is the development of an experimental quantum information processor based on trapped ions.

Aims and objectives

The aim is to build up a new experimental apparatus in which manipulation of ions by microwave fields is the main method to implement quantum logic.

Novelty of the research methodology

The near-field microwave method is itself relatively novel, having been exhibited at high fidelity in only one laboratory to date. A major feature of the new apparatus is a cryogenic system which will reduce electric field noise and permit lower background pressure to be reached.

Alignment to EPSRC's strategies and research areas (which EPSRC research area her project relates to)

Fundamental physics; information technology.

Description My research team has been able to trap and efficiently cool ions of the Ca43 isotope using lasers at a field of 28.8 mT for the first time. We have also been able to perform coherent qubit operations via microwaves.
Exploitation Route The progress so far shows that Ca43 ions at this magnetic field strength are viable candidates for quantum computing.
