论文摘要
频率依赖性挤压真空的应用将光学机械干涉仪的力敏感性提高了标准量子限制的$ e^{ - r} $，其中$ r $是挤压参数。在这项工作中，我们表明，挤压光以及量子光学恢复力的应用可以提高敏感性超过标准量子限制的$ \ sqrt {e^{ - 2r}ζ/4Δ} $，其中$ 0 <ζ/Δ<1 $，$ 0 <ζ/Δ<1 $，$ quun os $ζ$ quut a $Δ$Δ$Δ驾驶场。本文中描述的技术仅限于频率比光机械镜的共振频率小得多。
Application of frequency-dependent squeezed vacuum improves the force sensitivity of optomechanical interferometer beyond the standard quantum limit by a factor of $e^{-r}$, where $r$ is the squeezing parameter. In this work, we show that the application of squeezed light along with quantum optical restoring force can enhance the sensitivity beyond the standard quantum limit by a factor of $\sqrt{e^{-2r}ζ/4Δ}$, where $0< ζ/Δ<1$, with $ζ$ as the optomechanical cavity decay rate and $Δ$ as the detuning between cavity eigenfrequency and driving field. The technique described in this article is restricted to frequencies much smaller than the resonance frequency of the optomechanical mirror.
