In article number 2200130, Xu-Tao Yu and co-workers use the DNA-like double helix to represent the structure of parameterized quantum circuit, which corresponds to the design of revised multiobjective genetic algorithm. The split circuit fragment at the end of double helix represent the optimization of the structure of parameterized quantum circuit. There are two guide lines colored by red and blue represent the two objectives (gradient and cost) to be optimized.
