Noiseless phase quadrature amplification via electro-optic feed-forward
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.Comment: 8 pages, 4 figure
Coherent analysis of quantum optical sideband modes
We demonstrate a device that allows for the coherent analysis of a pair of
optical frequency sidebands in an arbitrary basis. We show that our device is
quantum noise limited and hence applications for this scheme may be found in
discrete and continuous variable optical quantum information experiments.Comment: 3 pages, 3 figures, submitted to Optics Letter
