经由电光前馈的无噪声相位正交放大
Noiseless phase quadrature amplification via electro-optic feed-forward
摘要：
理论结果表明，无噪声相位正交放大是可能的，和实验上仅限于相位检测系统的效率。用Nd：YAG激光器测得的信号增益为10dB，信号传输比T_s=0.9。这个结果很容易超过信号传输的标准量子极限。结果还明确地证明了放大过程的相敏性质。
英文摘要：
Theoretical results are presented which show that noiseless phase quadrature amplification is possible, and limited experimentally only by the efficiency of the phase detection system. Experimental results obtained using a Nd:YAG laser show a signal gain of 10dB and a signal transfer ratio of T_s=0.9. This result easily exceeds the standard quantum limit for signal transfer. The results also explicitly demonstrate the phase sensitive nature of the amplification process.
