▎ 摘  要

NOVELTY - The method involves receiving a microwave signal and two optical signals by a graphene structure, i.e. superconducting capacitor (100), and generating an entanglement, i.e. continuous variable two-mode squeezed entangled state, between two optical signals and the microwave signal by the graphene structure. An unknown coherent state is teleported based on the entanglement, where the teleporting is based on a fidelity greater than two-third. USE - Electronic method for generating a continuous variable two-mode squeezed entangled state between two optical fields independent of each other in a hybrid optical-microwave plasmonic graphene waveguide system. Uses include but are not limited to quantum teleportation, satellite quantum communications, submarine quantum communication, quantum internet, quantum error correction, and quantum cryptography. ADVANTAGE - The method enables controlling and enhancing the continuous-variable entanglement, i.e. teleportation fidelity through the interaction of the microwave mode with the two optical modes. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene structure. 100Superconducting capacitor
