Soliton 振幅挤压的状态被使用不对称的 Sagnac 获得并且检测干涉仪和平衡 homodyne 检测系统。为量状态察觉的一个改进相片察觉者电路被介绍。电路有 10MHz 的带宽,浸透力量是大约 19 mW。在射击噪音下面的 1.1 dB 的最大的光电流噪音减小被完成。考虑察觉效率,压榨将是大约 1.5 dB。
Soliton amplitude squeezed state is obtained and dctected by using asymmetric Sagnac interferometer and balanced homodyne detecting system. An improved photo detector circuit for quantum state detection is introduced. The circuit has a bandwidth of 10MHz and the saturation power is about 19 mW. A maximum photocurrent noise reduction of 1.1 dB below the shot noise is achieved. Taking the detection efficiency into account, the squeezing will be about 1.5 dB.
