Mixed-State Berry Curvature in quantum multiparameter estimations
Xiaoguang Wang, Xiao-Ming Lu, Yunbo Zhang +2
For pure states, the quantum Berry curvature was well studied. However, the quantum curvature for mixed states has received less attention. From the concept of symmetric logarithmi…
Joint optimal measurement for locating two incoherent optical point sources near the Rayleigh distance
Yingying Shi, Xiao-Ming Lu
The simultaneous optimization of the centroid estimation and the separation estimation of two incoherent optical point sources is restricted by a tradeoff relation through an incom…
Direct measurement of quantum Fisher information
Xingyu Zhang, Xiao-Ming Lu, Jing Liu +2
In the adiabatic perturbation theory, Berry curvature is related to the generalized force, and the quantum metric tensor is linked with energy fluctuation. While the former is test…
Performance-tradeoff relation for locating two incoherent optical point sources
Jingjing Shao, Xiao-Ming Lu
The optimal quantum measurements for estimating individual parameters might be incompatible with each other so that they cannot be jointly performed. The tradeoff between the estim…
Quantum Cramér-Rao bound for quantum statistical models with parameter-dependent rank
Yating Ye, Xiao-Ming Lu
Recently, a widely-used computation expression for quantum Fisher information was shown to be discontinuous at the parameter points where the rank of the parametric density operato…
Generalization of Rayleigh's Criterion on Parameter Estimation with Incoherent Sources
Lijun Peng, Xiao-Ming Lu
The basic idea behind Rayleigh's criterion on resolving two incoherent optical point sources is that the overlap between the spatial modes from different sources would reduce the e…
