    "abstract": "The quantum state transmission (QST) through the medium of high-dimensional\nmany-particle system is studied with a symmetry analysis. We discover that, if\nthe spectrum matches the symmetry of a fermion or boson system in a certain\nfashion, a perfect quantum state transfer can be implemented without any\noperation on the medium. Based on this observation the well-established results\nfor the QST via quantum spin chains can be generalized to the high-dimensional\nmany-particle systems with pre-engineered nearest neighbor (NN) hopping\nconstants. By investigating a simple but realistic near half-filled\ntight-binding fermion system with uniform NN hopping integral, we show that an\narbitrary many-particle state near the fermi surface can be perfectly\ntransferred to its translational counterpart.",
