    "abstract": "We propose a solid state based protocol to implement the universal quantum\nstorage for electronic spin qubit. The quantum memory in this scheme is the\nspin wave excitation in the ring array of nuclei in a quantum dot. We show that\nthe quantum information carried by an arbitrary state of the electronic spin\ncan be coherently mapped onto the spin wave excitations or the magnon states.\nWith an appropriate external control, the stored quantum state in quantum\nmemory can be read out reversibly. We also explore in detail the quantum\ndecoherence mechanism due to the inhomogeneous couplings between the electronic\nspin and the nuclear spins.",
