Large distance continuous variable communication with concatenated swaps

摘要: The radiation–pressure interaction between electromagnetic fields and mechanical resonators can be used to efficiently entangle two light coupled the same mode. We analyze performance of this process under realistic conditions, we determine effectiveness resulting entanglement as a resource for quantum teleportation continuous-variable signals over large distances, mediated by concatenated swap operations. study sensitiveness protocol quality factor systems, its in non-ideal situations which losses reduced detection efficiencies are taken into account.
