QuanEstimation: An open-source toolkit for quantum parameter estimation

Quantum parameter estimation promises a high-precision measurement in theory, however, how to design the optimal scheme specific scenario, especially under practical condition, is still serious problem that needs be solved case by due existence of multiple mathematical bounds and optimization methods. Depending on scenario considered, different may more or less suitable, both terms computational complexity tightness bound itself. At same time, metrological schemes provided methods need tested against realization complexity, robustness, etc. Hence, comprehensive toolkit containing various essential for quantum metrology. To fill this vacancy, here we present Python-Julia-based open-source estimation, which includes many well-used Utilizing toolkit, all procedures design, such as optimizations probe state, control measurement, can readily efficiently performed.
