Quantum entanglement in optical fiber

Abstract

Quantum entanglement is one of the deepest theory of quantum mechanics, with the field applications of quantum computation and quantum communication. The extended applications of entanglement generators are the LAN (local area network), MAN (metropolitan area network), and WAN (wide area network). All these optical, all-fiber network for quantum communication is necessary to accommodate high speed, high capacity and low losses. Also the other energy-time entangled qubits are considered good for quantum communication other than LAN regime. The entanglement generation and propagation in fibers are considered to be one of the most promising components of a potential long-distance quantum communication networks. Developing more accurate single photon emitters, faster single-photon detectors, and reliable quantum repeaters in addition to communication protocols optimized for realistic available devices are among the key targets to make quantum communication over long distances with higher bit rates.
