    "abstract": "In this paper, an optimal scheme of four-level quantum teleportation and\nswapping of quantum entanglement is given. We construct a complete orthogonal\nbasis of the bipartite ququadrit systems. Using this basis, the four-level\nquantum teleportation and swapping can be achieved according to the standard\nsteps. In addition, associate the above bases with the unextendible product\nbases and the exact entanglement bases, we prove that in the $2\\times 2\\times\n2$ systems or $3\\times 3$ systems the collective translations of multipartite\nquantum entanglement can be realized.\n  PACC numbers: 03.67.Mn, 03.65.Ud, 03.67.Hk.\n  Keywords: Ququadrit systems, Bases, Four-level teleportation, Swapping,\nCollective translations.",
