摘      要：We discuss the problem of identification of the dynamical generators for open two-level quantum systems in a Markovian *** on Bloch sphere representation,the identification problem is converted to the estimation of a 3-dimensional real process matrix A and an inhomogeneous term *** parameter identifiability and sufficient conditions for completely identification of A and c are *** discussion shows that the obtained sufficient conditions are not always *** approach can be generalized to finite-level open quantum systems in an arbitary Markovian environment.
