Three particle Hyper Entanglement: Teleportation and Quantum Key Distribution (1311.7318v5)
Published 28 Nov 2013 in quant-ph and cs.CR
Abstract: 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.
