Abstract: By utilizing the four-qubit cluster state as quantum channel, two efficient quantum schemes for teleporting an arbitrary single-qubit state in a controlled manner are put forward. In one scheme the controller needs to dominate a… read more here.

Abstract: We show that the standard 1+1D Z_{2}×Z_{2} cluster model has a noninvertible global symmetry, described by the fusion category Rep(D_{8}). Therefore, the cluster state is not only a Z_{2}×Z_{2} symmetry protected topological (SPT) phase, but… read more here.

Abstract: Quantum information splitting (QIS) provides an idea for transmitting the quantum state through a classical channel and a preshared quantum entanglement resource. This paper presents a new scheme for QIS based on a five-qubit cluster… read more here.
