The problem of model discriminability and parameter identifiability for dephasing two-level systems subject to Hamiltonian control is studied. Analytic solutions of the Bloch equations are used to derive explicit expressions for observables as functions of time for different models. This information is used to give criteria for model discrimination and parameter estimation based on simple experimental...
We discuss the problem of identification of the dynamical generators for open two-level quantum systems in a Markovian environment. Based on Bloch sphere representation, the identification problem is converted to the estimation of a 3-dimensional real process matrix A and an inhomogeneous term c. The parameter identifiability and sufficient conditions for completely identification of A and c are...
The identiflability of model parameters for open quantum systems is a crucial prerequisite for quantum control. By investigating two-level dephasing open quantum systems, we discuss under which conditions the information about Hamilto-nian and dephasing parameters can be obtained. Using simulated experiments Time-series analysis and Bayesian strategy for extracting model parameters from limited and...
This paper explores the experimental design and identifiability problems for both closed and open quantum systems. In general, the identifiability of quantum systems depends on both the choice of model sets and experimental design. The limits of identifiability in certain experimental settings and ways to improve the identifiability of model parameters by changing experimental conditions are investigated...
