Extending quantum sensing to time-varying parameter estimation is a potential and challenging task in practical application. To achieve this goal, we propose an adaptive method to estimate an unknown time-varying parameter through light-intensity split detection and the insertion of reference phases in the weak measurement. Theoretical analysis and numerical simulation are applied to illustrate the feasibility and practical applications of our method. The results demonstrate that the method has adjustable sensitivity and linear dynamic range, and is robust to nonideal measurement conditions. Moreover, we analyze the precision of our method and show that its precision limit can surpass the standard quantum limit and approach the Heisenberg scaling when using a squeezed light of optimal Gaussian state.

Surpassing the Nyquist sampling limit to avoid aliasing distortion is an important issue for the task of time-varying parameter estimation. To achieve this goal, we propose a high-precision time-varying parameter estimation scheme based on split detection and postmodulation of light instead of postprocessing of data. Theoretical analysis demonstrates its advantage of surpassing the Nyquist sampling limit and the avoidance of anti-aliasing distortion. In order to illustrate the feasibility, a numerical simulation based on the acceptance rejection sampling method is performed showing the noise robustness of the scheme in terms of correlation coefficient, root-mean-square error, and mean absolute error. Our scheme provides a method for function estimation.
