    "abstract": "We study the quantum state transfer (QST) of a class of tight-bonding Bloch\nelectron systems with mirror symmetry by considering the mode entanglement.\nSome rigorous results are obtained to reveal the intrinsic relationship between\nthe fidelity of QST and the mirror mode concurrence (MMC), which is defined to\nmeasure the mode entanglement with a certain spatial symmetry and is just the\noverlap of a proper wave function with its mirror image. A complementarity is\ndiscovered as the maximum fidelity is accompanied by a minimum of MMC. And at\nthe instant, which is just half of the characteristic time required to\naccomplish a perfect QST, the MMC can reach its maximum value one. A large\nclass of perfect QST models with a certain spectrum structure are discovered to\nsupport our analytical results.",
