Abstract: In this paper, a novel scheme is investigated for quantum teleportation (QT) and
quantum state sharing (QSTS). The generalized seven-qubit Brown state |B7⟩ is used as
information carrier. Firstly, for an arbitrary single-qubit state, we perfectly present a QT
protocol and three QSTS ones, which is among three participants via |B7⟩. Then we make an
