Quantum Metrology of Absorption and Gain Parameters using Two-Mode Bright Squeezed Light
arXiv:2404.00871 · doi:10.1103/PhysRevA.109.053715
Abstract
Absorption and gain processes are fundamental to any light-matter interaction and a precise measurement of these parameters is important for various scientific and technological applications. Quantum probes, specifically the squeezed states have proved very successful, particularly in the applications that deal with phase shift and force measurements. In this paper, we focus on improving the sensitivity of the estimation of the photon loss coefficient of a weakly absorbing medium as well as the estimation of the gain parameter using a two-mode bright squeezed state. The generation of this state combines the advantage of a coherent beam for its large photon number with the quantum properties of the two-mode squeezing operation in an optical parametric amplifier. We present two measurement schemes: balanced photodetection and time-reversed metrology, both utilizing two-mode bright squeezed light. The maximum quantum advantage we can achieve using two-mode bright squeezed light is 3.7 times for the absorption parameter and 8.4 times for as compared to using only the coherent state. Similarly, the maximum quantum advantage for the estimation of optical gain is found around 2.81 times for the gain coefficient and around 6.28 times for . We discuss the significance of using one measurement scheme over the other under different squeezing conditions. We compare our results with the Cramér-Rao bound for a two-mode bright squeezed state to assess the quality of the proposed methodologies.
