Our paper on Microgram BaCl_2 Ablation Targets for Trapped Ion Experiments has been published in Review of Scientific Instruments! This is an experimental work from the QuantumIon project.
Our paper investigating 2D ion crystals in a hybrid optical cavity trap has been published in PRA! This is a theoretical and numerical work.
Abstract: Trapped ions for quantum information processing has been an area of intense study due to the extraordinarily high fidelity operations that have been reported experimentally. Specifically, barium trapped ions have been shown to have exceptional state-preparation and measurement (SPAM) fidelities. The 133Ba+ (I=1/2) isotope in particular is a promising candidate for large-scale quantum computing experiments.
Abstract: We numerically investigate a hybrid trapping architecture for 2D ion crystals using static electrode voltages and optical cavity fields for in-plane and out-of-plane confinements, respectively. By studying the stability of 2D crystals against 2D-3D structural phase transitions, we identify the necessary trapping parameters for ytterbium ions. Multiple equilibrium configurations for 2D crystals are possible, and we analyze their stability by estimating potential barriers between them.
Trapped ion quantum computers represent a cutting-edge quantum computing platform, keeping the highest reported state preparation and measurement fidelity of 99.97%. Recently, barium ion has emerged as the research interest of several teams due to its exceptional characteristics, including visible and inferred state transition frequencies, long-lived metastable states, and a simple hyperfine structure.
