It is demonstrated that high-Q (Q～108) bottle microresonators can be fabricated by using a CO2 laser to heat a vertical single-mode fiber with a small weight attached to its lower end. A tunable continuous-wave laser is used to excite whispering-gallery modes in a bottle microresonator through a fiber taper, and a ringing phenomenon is observed. The observed ringing phenomenon is well explained through the numerical solution of a dynamic equation. In addition, an explicit function is given to describe the light field in the resonator, and the theoretical transmission based on the function also agrees very well with the experimental ringing phenomenon.

研究非Bell基测量的未知三粒子W态的隐形传态方案。先利用原子和腔场的共振相互作用制备未知三原子W态。接着，利用两原子同时在强经典驱动场驱动下和单模腔场发生相互作用，产生态的演化，来制备EPR对量子信道。最后利用和制备量子信道同样的方法来实现未知三原子W态的隐形传送。在传送过程中，可忽略腔场热作用和腔延迟作用的影响。传送成功的总几率为1。
