Abstract :
A scheme is proposed for preparing the superposition of two-mode coherent states with controllable weighting factors along a straight line for two-mode cavity field. In this scheme two-level atoms driven by classical field are sent through a two-mode cavity initially in the vacuum state. Then the detection of the atoms make the cavity field be in a two-mode superpositions of coherent states.

Abstract :
We propose two schemes for quantum information splitting via W-class state. The first scheme is based on the interaction of single atom with single-mode field, while the second scheme is based on the simultaneous interaction of two atoms with single-mode cavity. For the first scheme, the difficulty of two atoms required to be simultaneously sent through one cavity is avoid. For the second scheme, it is immune to thermal field. Both schemes are experimentally feasible based on current cavity QED techniques.

Abstract :
Using gas-state reaction, Nanometer WO3 was synthesized by gasstate reaction with tungsten filament, WO3 mixed with TiO 2 made by Sol-gel method was made up into gas-sensor to H 2S. The gas-sensing measurement results revealed that these sensors with a certain sensitivity put into H2S gas of density (about 10 -6) and present good response-recovery characteristics. By analyzing micro-structure of the material, the mechanism of these sensors was discussed.
