Long-distance communication

Architectures for Long-Distance Quantum Communication

A quantum communication system that is capable of long-distance, highfidelity teleportation, and long-duration quantum storage is proposed. This system uses polarization-entangled photons and trapped-atom quantum memories and is compatible with transmission over standard telecommunication fiber. An extension of this architecture permits long-distance transmission and storage of Greenberger-Horn...

Optimal architectures for long distance quantum communication

Despite the tremendous progress of quantum cryptography, efficient quantum communication over long distances (≥ 1000 km) remains an outstanding challenge due to fiber attenuation and operation errors accumulated over the entire communication distance. Quantum repeaters (QRs), as a promising approach, can overcome both photon loss and operation errors, and hence significantly speedup the communi...

Long-Distance Communication between Laryngeal Carcinoma Cells

Tunneling nanotubes and epithelial bridges are recently discovered new forms of intercellular communication between remote cells allowing their electrical synchronization, transfer of second messengers and even membrane vesicles and organelles. In the present study, we demonstrate for the first time in primary cell cultures prepared from human laryngeal squamous cell carcinoma (LSCC) samples th...
