Non-asymptotic analysis of quantum metrology protocols beyond the Cramér-Rao bound

Many results in the quantum metrology literature use the Cramér-Rao bound and the Fisher information to compare different quantum estimation strategies. However, there are several assumptions that go into the construction of these tools, and these limitations are sometimes not taken into account. Wh...
