We propose a scheme to manipulate a kind of topological spin qubits realized with cold atoms in a one-dimensional optical lattice. In particularly, by introducing a quantum optomechanical setup, we are able to fist transfer a superconducting qubit state to an atomic state and then to store it into the topological spin qubit. In this way, an efficient topological quantum memory may be constructed for the superconducting qubit. Therefore, we can consolidate the advantages of both the noise resistance of topological qubits and the scalability of superconducting qubits in this hybrid architecture.
