Three particle Hyper Entanglement: Teleportation and Quantum Key Distribution

30 Jun 2015  ·  Chithrabhanu P., Aadhi A., Reddy Salla Gangi, Prabhakar Shashi, Samanta G. K., Paul Goutam, Singh R. P. ·

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. read more
