A scheme of teleportation of a tripartite state via W state is suggested. The W state serves as quantum channels. Standard Bell-state measurements and Von Neumann measurements are performed. After the sender operates the measurements and informs the receiver her results, he can reconstruct the original state by the corresponding unitary transformation. The probability of the successful teleportation is also obtained.

Teleportation schemes with a five-atom entangled state are investigated. In the teleportation scheme Bell state measurements （BSMs） are difficult for physical realization, so we investigate another strategy using separate measurements instead of BSM based on cavity quantum electrodynamics techniques. The scheme of two-atom entangled state teleportation is a controlled and probabilistic one. For the teleportation of the three-atom entangled state, the scheme is a probabilistic one. The fidelity and the probability of the successful teleportation are also obtained.

A scheme for implementing discrete quantum Fourier transform is proposed via quantum dots embedded in a microcavity, and then some of its applications are investigated, i.e., Deutsch 3ozsa. algorithm and Shor＇s quantum factoring. In particular, the detailed process of implementing one^qubit Deutsch Jozsa algorithm and the factorization of N = 15 are given. The microcavity mode is only virtually excited in the whole interaction, so the effective decoherent has slight effect on the current scheme. These schemes would be an important step to fabricate a solid quantum computer.

Otolith morphology is widely used for fish stock identification. The sulcus, a structure on the medial side of the otolith, is an important feature in morphological analysis. This study was conducted to evaluate the feasibility of using sulcus morphology for stock identification and to compare its performance with commonly used otolith morphology analysis. Otoliths were collected and analyzed from three geographical groups (the Huanghe (Yellow) River estuary, HHE;the Jiaozhou Bay, JZB;and the Changjiang (Yangtze) River estuary, CJE) of yellow drum Nibea albiflora. The results show that the analysis of sulcus morphology based on shape indices (SIs), elliptic Fourier coefficients (EFc), and a combination of the two parameters identified stocks at overall classification rates of 51.0%, 72.5%, and 73.2%, respectively. These classification rates are similar to those obtained using otolith morphology analysis (57.0%, 73.8%, and 76.5% by SIs, EFc, and their combination, respectively). The findings suggest that sulcus morphology is comparable to the commonly used otolith morphology for identifying stocks of sciaenids, such as the yellow drum. For both otolith and sulcus morphology, EFc could identify the stocks more efficiently than SIs, while the combination of SIs and EFc was even better.

Rechargeable Mg batteries(RMBs)are a promising large-scale energy-storage technology with low cost and high safety,but the performance is limited by the inferior kinetics of Mg-intercalation *** the present study,an octylamine-supporting interlayer expanded molybdenum diselenide(e-MoSe_(2))is synthesized and used as cathode for RMBs,in comparison with ordinary crystalline MoSe_(2).The octylamine molecules introduced show a strong interaction with the MoSe_(2)layers and increase the layer spacing significantly from 6.46 to 11.5Å.e-MoSe_(2)shows a high Mg-storage capacity of 238 mAh g^(-1)at 50 mA g^(-1)and a superior rate performance of 39 mAh g^(-1)at 10 A g1,far advantageous over crystalline MoSe_(2).e-MoSe_(2)also shows a considerably high structure stability during repeated magnesiation/demagnesiation,providing an outstanding cycling stability for 1000 *** electrochemical tests demonstrate the high Mg^(2+)diffusion coefficients in e-MoSe_(2).Theoretical computation indicates the interlayer expansion changes the Mg^(2+)diffusion paths from"hollow site→hollow site"to"hollow site→Se atom site→hollow site",largely decreasing the energy barrier and improving the Mg^(2+)diffusion *** present work highlights an efficient strategy for the improvement of Mg-storage performance for RMB cathodes.

We propose a scheme for controlled entanglement swapping of continuous variable, where an EPR pair shared by two parties （Alice and Debbie） and a GHZ entangled state shared by three parties （Alice, Bob and Claire） are required. One optical beams of the EPR state will be entangled with the output mode displaced by Bob with the help of Claire. It is shown that the entanglement swapping can occur controlled by the third party （Claire）
