Abstract

Maximum-likelihood estimation is applied to identification of an unknown quantum mechanical process. In contrast to linear reconstruction schemes the proposed approach always yields physically sensible results. Its feasibility is demonstrated by means of Monte Carlo simulations for the two-level system (single qubit).
