We investigate the efficiency of periodic dynamical decoupling of an exciton qubit confined in a selfassembled quantum dot in the presence of an applied electric field. The shape of the quantum dot is found to have a large effect on the excitonic dephasing. It is shown that dynamical suppression of
Finite mixtures of Markov processes with densities belonging to exponential families are introduced. Quasilikelihood and maximum likelihood methods are used to estimate the parameters of the mixing distributions and of the component distributions. The E-M algorithm is used to compute the ML estimate
