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: Protecting qubits from accidental measurements is essential for controlled quantum operations, especially during state-destroying measurements or resets on adjacent qubits, in protocols like quantum error correction. Current methods to preserve atomic qubits against such disturbances waste coherence time, extra qubits, and introduce additional errors. We demonstrate the feasibility of in-situ state-reset and state-measurement of trapped ions, achieving >99.
Abstract: We propose and experimentally demonstrate an analog scheme for generating XY-type (Jx XX + Jy YY) Hamiltonians on trapped ion spins with independent control over the Jx and Jy terms. The Ising-type interactions σixσjx and σiyσjy are simultaneously generated by employing two spin-dependent forces operating in parallel on the same set of normal modes.
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.
