在介观耗散传输线量子化的基础上,研究了振幅薛定谔猫态下该传输线的压缩特性.结果表明,传输线中电流及单位长度传输线电感上电压的量子噪声的压缩性质不仅取决于振幅薛定谔猫态,也与传输线的分布参数和位置有关.平均光子数为1时,量子噪声可得到最大压缩.

Besed upon the quantization of a mesoscopic dissipation transmission line, the squeezing effect of the line in the amplitude Schrodinger-Cat state was studied. It is shown that the compression feature of the line depend on not only the the amplitude Schrodinger-Cat state, but also the distribution parameters and positon of the line, the quantum noise can be farthest compressed when the average photon number is one.
