    "abstract": "We study quantum squeezing and entanglement of gap solitons in a\nBose-Einstein condensate loaded into a one-dimensional optical lattice. By\nemploying a linearized quantum theory we find that quantum noise squeezing of\ngap solitons, produced during their evolution, is enhanced compared with the\natomic solitons in a lattice-free case due to intra-soliton structure of\nquantum correlations induced by the Bragg scattering in the periodic potential.\nWe also show that nonlinear interaction of gap solitons in dynamically stable\nbound states can produce strong soliton entanglement.",
