摘要 We have investigated the intrinsic decoherence on the entanglement of a two-qutrit one-dimensional （1D） optical lattice chain with nonlinear coupling. As a measure of the entanglement, the negativity of the system is calculated. It is shown that the influence of intrinsic decoherence on the entanglement varies in different initial systems.
