| 摘 要： | 利用热场动力学的方法计算了热压缩态中测量相位算符的涨落，引入了两种类型的基础量子涨落，一种是与测量相位的两个正交分量相联系，另一种是与一个测量相位分量和光子数相联系。由此，研究了热压缩压中测量相位涨落的两种压缩及其与温度的关系。

| Abstract: | The quantum correlated twin beams have bean generated by an optical parametric oscillator with a pair of KTP crystals, the total power of the output twin beams is 23 mW at the pump power of 300 mW. he quantum noise reduction of 50% (3 dB) in the intensity difference between the twin beams was observed near 1.25 MHz. |
| |
| Keywords: | parametric down conversion twin beams the squeezing of the intensity difference. |
