|Y> state distillation circuit using lattice surgery multi-target CNOTs was implemented and evaluated in a logical qubit architecture consisting of 24 logical qubits for two different qubit arrangements. Lattice surgery multi-target CNOTs and logical S gates are performed on each arrangement. In the second arrangement, the first and fourth multi-target CNOTs are split into two CNOTs because it takes over 1TB of memory to initialize a rectangular ancilla qubit of six lattices to |+>. These operations are performed for |Y> state distillation process. The time cost is given for logical operations by d rounds ESM cycle of surface code logical qubit.
