In this paper we report the optimal design and fabrication of a gold-on-silica linear segmented surface-electrode ion trap. By optimizing the thickness and width of the electrodes, we improved the trapping ability and trap scalability. By using some practical experimental operation methods, we successfully minimized the trap heating rate. Consequently, we could trap a string of up to 38 ions, and a zigzag structure with 24 ions, and transport two trapped ions to different zones. We also studied the influences of the ion chip surface on the ion lifetime. The excellent trapping ability and flexibility of operation of the planar ion trap shows that it has high feasibility for application in the development a practical quantum information processor or quantum simulator.

Extension of Linear Response Regime in Weak-Value Amplification Technique

第十八届全国量子光学学术会议

作者：张满超 Chunwang Wu Yi Xie Wei Wu pingxing chen 中国人民解放军国防科学技术大学 Department of Physics College of Liberal Arts and SciencesNational University of Defense Technology

We have investigated how the quantum state is protected by incomplete projective measurements, where the system evolution from this quantum state is monitored by measuring apparatuses but the coherence of the system is not completely eliminated during each measuring process. We show that the system evolution from the quantum state can always be partially inhibited. And interestingly, if the Bloch vector experiences a rotation around σ axis during measurement processes, a more efficient freezing of quantum state, than the ideal measurements case, may also be realized.

从“齐二药”案的判决反思医院药品使用的归责问题

第十八届全国量子光学学术会议

作者：张杰 Yi Xie Chun-wang Wu Bao-quan Ou Wei Wu pingxing chen 国防科大 Department of Physics National University of Defense Technology

In this paper we report an experimental implementation of adiabatic search algorithm on a two-bit data base with shortcut to adiabaticity（STA） in an ion trap system. Initially the data base is created by applying a pi/2 laser pulse on a single qubit, and following the driving Hamiltonian leads the system evolving from data base to target state. To speed up the searching process and force the system evolution to follow the adiabatic path, we use the STA method which suppresses the non-adiabatic transitions and shortens the searching time by at least 4 times compared to the conventional adiabatic method. In our experiment target state is searched with fidelity better than 98%.
