从光机械诱导透明度的角度出发,提出了一种在单纳米机械谐振器(NAMR)光机械系统中利用压缩场进行精确温度测量的方案。我们证明了压缩场的温度测量方案可以抵抗腔衰减,甚至可以在单光子水平上实现。此外,我们表明,与之前发表的文献(Wang et al . 2015 Phys. 5)中报道的耦合双namr光力学系统相比,Rev. A 91 063827),我们的方案在单NAMR系统中具有相同的阶数测量灵敏度,但具有更长的测量范围,而与单NAMR系统中的经典场相比,我们的方案在压缩场中具有相同的测量范围,但具有更高的阶数测量灵敏度。
We present a scheme for precision temperature measurement with a squeezed field in a single nano-mechanical resonator (NAMR) optomechanical system in terms of optomechanically induced transparency. We demonstrate that the temperature measurement scheme with a squeezed field can be robust against cavity decay and can even be implemented with a single photon level. In addition, we show that, compared with the coupled two-NAMR optomechanical system reported in a previous publication (Wang et al 2015 Phys. Rev. A 91 063827), our scheme with a single NAMR can present the same order measurement sensitivity, but with a longer measurement range, while, compared with the case of a classical field in single-NAMR system, our scheme with a squeezed field can show the same measurement range, but with a higher order measurement sensitivity.
