  We present a scheme to generate three particle hyper-entanglement utilizing
polarization and orbital angular momentum (OAM) of a photon. We show that the
generated state can be used to teleport a two-qubit state described by the
polarization and the OAM. The proposed quantum system has also been used to
describe a new efficient quantum key distribution (QKD) protocol. We give a
sketch of the experimental arrangement to realize the proposed teleportation
and the QKD.
