Abstract: | A new application of the four-qubit cluster state is investigated for quantum information splitting (QIS) of an arbitrary
three-qubit state. Muralidharan and Panigrahi (Phys Rev A 78:062333, 2008) argued that a four-qubit cluster state is impossible
for QIS of an arbitrary two-qubit state. In this paper, we demonstrate that two four-qubit cluster states can be used to realize
the deterministic QIS of an arbitrary three-qubit state by performing only the Bell-state measurements. Our scheme considered
here is secure against certain eavesdropping attacks. |
