Modeling noise in global Mølmer-Sørensen interactions applied to quantum approximate optimization

Many-qubit M\o{}lmer-S\o{}rensen (MS) interactions applied to trapped ions offer unique capabilities for quantum information processing, with applications including quantum simulation and the quantum approximate optimization algorithm (QAOA). Here, we develop a physical model to describe many-qubit MS interactions under four sources of experimental noise: vibrational mode frequency fluctuations, laser power …
