    "abstract": "The bounds on concurrence of the superposition state in terms of those of the\nstates being superposed are studied in this paper. The bounds on concurrence\nare quite different from those on the entanglement measure based on von Neumann\nentropy (Phys. Rev. Lett. 97, 100502 (2006)). In particular, a nonzero lower\nbound can be provided if the states being superposed are properly constrained.",
