| Research Abstract |
A positive operator valued measure (POVM) is a measurement in the quantum information theory. An informationally complete POVM allows one to estimate the expectation value of any arbitrary operator. In the present study, we construct some examples of informationally complete POVMs and we show that there exists an operator space which does not have a good informationally complete POVM.
