# Qutrit: entanglement dynamics in the finite qutrit chain in the consistent magnetic field

@article{Ivanchenko2011QutritED, title={Qutrit: entanglement dynamics in the finite qutrit chain in the consistent magnetic field}, author={E. A. Ivanchenko}, journal={arXiv: Quantum Physics}, year={2011} }

Based on the Liouville-von Neumann equation, we obtain closed system of equations for the description of a qutrit or coupled qutrits in arbitrary time-dependent external magnetic field. The dependence of the dynamics on the initial states and magnetic field modulation is studied analytically and numerically. We compare the relative entanglement measure's dynamics in the bi-qutrit system with permutation particle symmetry. We find the magnetic field modulation which retains the entanglement in… Expand
