    "abstract": "By using the partial transpose and realignment method,we study the time\nevolution of the bound entanglement under the bilinear-biquadratic Hamiltonian.\nFor the initial Horodecki\u0027s bound entangled state, it keeps bound entangled for\nsome time, while for the initial bound entangled states constructed from the\nunextendable product basis, they become free once the time evolution begins.\nThe time evolution provides a new way to construct bound entangled states, and\nalso gives a method to free bound entanglement.",
