1D systems exhibiting a continuous symmetry can host exotic quantum phases of matter with true long-range order, but they require long-range interactions. We individually control all the spins in a chain of trapped ions, and their inherent long-range interactions allow the study of such CSB phases with up to 23 spin/qubits.
