Abstract:The corresponding quantum state estimation methods and their application backgrounds in four measurement situations are reviewed. The methods involve the typical methods broadly used in experimental quantum field and the state estimation methods which are based on systematic perspective and applicable to quantum feedback control. Eessentially, the estimation principle of every method is explained by stating its development process, and the corresponding analysis and comparison in technology are given. Finally, the quantum state estimation is compared with the corresponding classical state estimation, and some comments on state estimation methods in quantum systems are summarized.
Keywords:Quantum system  State estimation  Measurement situation  Initial state estimation  Feedback state estimation
