Metastable Quibits in Multi-Ion Systems
Abstract
While all of the basic primitives required for universal quantum computing have been demonstrated in trapped-ion qubits with high fidelity, it is currently not possible to simultaneously realize the highest achieved fidelities in a single ion species. This is a serious impediment to the development of practical quantum computers. However, there are possibilities for achieving high-fidelity, full functionality in a single species: augmentation of existing species with new functionality and synthesis of new species with advanced capabilities. This program will pursue both tracks with a firm grounding in the practical context of gate-based processing in multi-ion arrays. Specifically, essential dual-species capabilities will be developed--in both synthetic and naturally occurring single-ion species--through novel encoding schemes in metastable states, allowing user-selectable, ion-specific activation of the necessary functions on demand (e.g. storage, coupling to motion, cooling, and state preparation and measurement). We will work to achieve these needed capabilities in realistic, multi-ion arrays, demonstrating the essential building blocks for practical, intermediate-size quantum processors.
