DOI: 10.1007/s10773-019-04089-5
Abstract: A scheme of circular controlled quantum teleportation, which is a novel version of bidirectional controlled quantum teleportation, is proposed using a specific genuine seven-qubit entangled state as quantum channel, and then it is generalized to… read more here.
