Abstract
A new application of the four-qubit cluster state is investigated for quantum information splitting (QIS) of an arbitrary N-qubit GHZ-type state among three parties. We demonstrate that a four-qubit cluster state can be used to realize the deterministic QIS of an arbitrary N-qubit GHZ-type state by introducing N−1 ancillary qubits and performing N−1 controlled-NOT operations. The presented protocols considered here are secure against certain eavesdropping attacks.
