    "abstract": "The entanglement between spins of a pair of particles may change because the\nspin and momentum become mixed when viewed by a moving observer [R.M. Gingrich\nand C. Adami, Phys. Rev. Lett. 89, 270402 (2002)]. In this paper, it is shown\nthat, if the momenta are appropriately entangled, the entanglement between the\nspins of the Bell states can remain maximal when viewed by any moving observer.\nFurther, we suggest a relativistic-invariant protocol for quantum\ncommunication, with which the non-relativistic quantum information theory could\nbe invariantly applied to relativistic situations.",
