TELEPORTATION CAPABILITY OF FOUR-QUBIT CLUSTER STATE IN ONE-VERSUS-THREE OR THREE-VERSUS-ONE QUBIT DISTRIBUTION
The capability of a one-dimensional four-qubit cluster state for teleportation is extensively investigated in the condition that the four qubits are non-averagely distributed between two locations. Because of the inherent qubit orientation of the cluster state, we found that only in eight distributions can an arbitrary single-qubit state be perfectly teleported from a sender to a receiver. For each case, the necessary local operations and classical communication (LOCC) are explicitly shown.
