| Abstract: | By virtue of the well-known concept of Fisher information in the theory of statistical inference, we obtain an inequality chain which generalizes and refines the conventional Heisenberg uncertainty relations. |
| Keywords: | Fisher information uncertainty relations Cramér-Rao inequality parameter estimation quantum measurement |
