| 英文摘要 | We propose a scheme for storing arbitrary states of two superconducting charge qubits in a single Rb-87 cold-atom ensemble. The information of the two charge qubits is transferred sequentially into the single atomic ensemble, via a transmission line resonator serving as "data bus." We simulate the storage process by integrating the master equation that takes into account all kinds of decoherence mechanisms, and show that the mean storage fidelity is very high with the present experimental parameters. Moreover, the storage efficiency of the single ensemble in our scheme is double that of previous schemes. Finally, we also briefly discuss the possibilities and difficulties of extending it to multiqubit cases. |
