N2 - Theoretical results are presented that 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 neodymium-doped yttrium aluminum garnet laser show a signal gain of 10 dB and a signal transfer ratio of [Formula Presented]. This result easily exceeds the standard quantum limit for signal transfer. The results also explicitly demonstrate the phase-sensitive nature of the amplification process.
