In this study, we present novel multi-mode qubit architectures designed using evolutionary algorithms that exhibit desirable qubit characteristics, including restricted transitions, improved relaxation and dephasing times, and resilience against fabrication defects. This approach is valuable for identifying configurations that, although lacking the complete protection of symmetry-protected systems, strike a balance between manipulability, construction, and noise protection.
