真空涨落与压缩光的条件零差探测

Vacuum fluctuations and the conditional homodyne detection of squeezed light

H J Carmichael, Hyunchul Nha

摘要:

正交压缩的条件零差检测与标准的无条件检测进行了比较。而后者以定量的方式识别非经典性,作为一个减少的噪声功率低于散粒噪声水平,条件检测真空态压缩和压缩经典噪声之间的定性区分。这种比较的现实解释真空波动(随机电动力学)的影响进行了讨论。

英文摘要:

Conditional homodyne detection of quadrature squeezing is compared with standard nonconditional detection. Whereas the latter identifies nonclassicality in a quantitative way, as a reduction of the noise power below the shot noise level, conditional detection makes a qualitative distinction between vacuum state squeezing and squeezed classical noise. Implications of this comparison for the realistic interpretation of vacuum fluctuations (stochastic electrodynamics) are discussed.
