Three particle Hyper Entanglement: Teleportation and Quantum Key Distribution
This work addresses challenges in quantum information processing by enabling advanced teleportation and secure communication, though it appears incremental as it builds on existing hyper-entanglement concepts.
The authors tackled the problem of generating and utilizing three-particle hyper-entanglement in photons, demonstrating its application for teleporting a two-qubit state and proposing an efficient quantum key distribution protocol, with a sketch of experimental realization provided.
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.
