Paper Abstract

The simultaneous inseparable reconstruction of quantum process and states is presented. The method is based on constrained extremization of the likelihood functional. This statistical approach is ingenuous in quantum mechanical frame and ensures physically correct results. Adopted scheme predicts the input density operators and the operator of quantum process all at once with help of noisy measured data only. Attention is paid to the comparison of posed method with sequential measurement of the states and the process. Method is illustrated by numerical simulations.
