| Outline of Final Research Achievements |
In this research project, the possibility to control and optimize non-classical correlations in quantum process was explored using new quantum statistical methods and their experimental implementations. The results show that non-classical correlations can be measured directly by weak measurements and related methods such as quantum cloning or quantum controlled measurements. Typically, non-classical correlations appear as imaginary parts of the statistics and indicate how the quantum system will respond to transformation processes. This insight into non-classical statistics has direct applications in the optimization of quantum processes, since it describes the effects of external forces on outcome efficiencies.
