Trapped atomic ions are an ideal platform for building novel quantum systems from the ground up. The combination of long-lived qubit coherence time and mature laser manipulation techniques compose the building blocks of a quantum computer. We use this toolbox to engineer interacting many-body systems, where the spins are encoded in atomic hyperfine states and entangled via the shared motional quantum bus. This has enabled long-range quantum Ising models with individual measurement and control, which are scaled up to 50+ spins, where the dynamics is hard to tract classically. We present applications of this quantum simulation platform for studying out of equilibrium phenomena, including discrete time crystals and dynamical phase transitions.
