Abstract: We introduce LYNX, a quantum information processor based on trapped $^{40}$Ca$^+$ ions. It utilizes up to 31 qubits with all-to-all connectivity. We characterize the system performance using rigorous benchmarks, such as randomized benchmarking (RB), GHZ state fidelity estimates, and quantum volume (QV) tests. The LYNX processor shows average 1-qubit gate errors of $8(5)\times 10^{-5}$ tested via standard RB in a 24-qubit register. An average 2-qubit gate error in a 24-qubit register of $2.84(8)\times 10^{-3}$ is demonstrated using interleaved RB. Furthermore, the device passes QV tests using up to 15 qubits which corresponds to a quantum volume of QV$=2^{15}$.
