Scaling trapped ion quantum information processing to large numbers of qubits relies on micro-fabricated traps optimized for the applications in quantum computing and quantum simulation.High trap frequencies and excellent optical access are the key features necessary for quantum information processing that are realized in Sandia's bowtie shaped High Optical Access trap.For quantum simulations long equidistant chains of ions, and ring-shaped crystals are of interest.Here, we demonstrate a chain of approximately 350 ions in a highly symmetric ring trap. Ring Trap10 mm Motivation • Large equidistant ion crystal • RF potential is sufficient to trap ion chain • Periodic boundary conditions • Possible applications: • phase transitions (E.
