The effect of stochastic dephasing on the entanglement and coherence of qutrits
چکیده انگلیسی
By using negativity, we study the effect on the quantum entanglement of 2-qutrit states of stochastic dephasing which obeys the stationary Gauss-Markov process. The linear entropy used to measure coherence loss due to the stochastic dephasing is discussed. With analysis, we find that the time evolution of entanglement and the linear entropy depends not only on the structure of states of concern, but also on the strength of the fluctuations of the random variable in the stochastic process.
