Suppose that we have a number of i.i.d. quantum states. By performing a measurement on each state, what information and how much information content about the system is obtained? Quantum estimation theory provides an answer to the question. In this chapter, we review quantum estimation theory [1, 2, 3] and introduce quantum Fisher information, which gives the upper bound of the classical Fisher information.
