Contribution

It provides a detailed analysis of collective oscillations, sympathetic cooling, and anharmonicity impacts on laser-cooling in mixed-species ion chains for quantum computing.

Findings

Enhanced understanding of sympathetic cooling efficiency.

Impact of anharmonicity on quantum information processing.

Characterization of collective oscillation modes.

Abstract

We study from the point of view of quantum logic the properties of the collective oscillations of a linear chain of ions trapped in a linear Paul trap and composed of two ion species. We discuss extensively sympathetic cooling of the chain and the effect of anharmonicity on laser-cooling and quantum-information processing.
