Abstract: | We investigate the usefulness of the highly entangled five-partite cluster and Brown states for the quantum information splitting
(QIS) of a special kind of two-qubit state using remote state preparation. In our schemes, the information that is to be shared
is known to the sender. We show that, QIS can be accomplished with just two classical bits, as opposed to four classical bits,
when the information that is to be shared is unknown to the sender. The present algorithm, demonstrated through the cluster
and Brown states is deterministic as compared to the previous works in which it was probabilistic. |
