Tight tradeoff relation and optimal measurement for multiparameter quantum estimation
Lingna Wang, Hongzhen Chen, Haidong Yuan
In multiparameter quantum estimation, the optimal measurements for different parameters encoded in a quantum state are in general incompatible, giving rise to nontrivial tradeoffs…
Minimal Trade-off and Optimal Measurement for Multiparameter Quantum Estimation
Lingna Wang, Hongzhen Chen, Haidong Yuan
A fundamental challenge in multiparameter quantum estimation arises from the incompatibility of optimal measurements for different parameters, leading to intricate precision trade-…
Stochastic Block Bregman Projection with Polyak-like Stepsize for Possibly Inconsistent Convex Feasibility Problems
Lu Zhang, Hongzhen Chen, Hongxia Wang +1
Stochastic projection algorithms for solving convex feasibility problems (CFPs) have attracted considerable attention due to their broad applicability. In this paper, we propose a…
Simultaneous Measurement of Multiple Incompatible Observables and Tradeoff in Multiparameter Quantum Estimation
Hongzhen Chen, Lingna Wang, Haidong Yuan
How well can multiple incompatible observables be implemented by a single measurement? This is a fundamental problem in quantum mechanics with wide implications for the performance…
