“…quantum repeaters (see Section VI.F) and distributed quantum computing (see Section VII). Rarity et al (1996) observed the interference between independent photons, one of which was a triggered single photon from a down-converted pair, and the other one was in an attenuated beam 17 derived from the pumping laser light. Interference of two triggered single photons created via parametric down-conversion by the same pump pulse passing twice through a nonlinear crystal was achieved in spatial wave function has to be antisymmetric, too .…”

Multi-photon interference reveals strictly non-classical phenomena. Its applications range from fundamental tests of quantum mechanics to photonic quantum information processing, where a significant fraction of key experiments achieved so far comes from multi-photon state manipulation. We review the progress, both theoretical and experimental, of this rapidly advancing research. The emphasis is given to the creation of photonic entanglement of various forms, tests of the completeness of quantum mechanics (in particular, violations of local realism), quantum information protocols for quantum communication (e.g., quantum teleportation, entanglement purification and quantum repeater), and quantum computation with linear optics. We shall limit the scope of our review to "few photon" phenomena involving measurements of discrete observables.

“…For example, phase measurement with super-sensitivity beyond the standard quantum limit (SQL) can be realized by using N-particles entangled state (N ≥ 2). [5][6][7][8] This has many important applications, including gravitational wave detection, measurements of distance and optical properties of materials, and chemical and biological sensing. Very recently, entanglement-enhanced microscopes, which give a signal-to-noise ratio better than that limited by the SQL, 9,10 have been realized.…”

Photonic quantum technologies have been extensively studied in quantum information science, owing to the high-speed transmission and outstanding low-noise properties of photons.However, applications based on photonic entanglement are restricted due to the diffraction limit. In this work, we demonstrate for the first time the maintaining of quantum polarization entanglement in a nanoscale hybrid plasmonic waveguide composed of a fiber taper and a silver nanowire. The transmitted state throughout the waveguide has a fidelity of 0.932 with the maximally polarization entangled state Φ + . Furthermore, the Clauser, Horne, Shimony, and Holt (CHSH) inequality test performed, resulting in value of 2.495 ± 0.147 > 2, demonstrates the violation of the hidden variable model. Since the plasmonic waveguide confines the effective mode area to subwavelength scale, it can bridge nanophotonics and quantum optics, and may be used as near-field quantum probe in a quantum near-field micro/nano-scope, which can realize high spatial resolution, ultra-sensitive, fiber-integrated, and plasmon-enhanced detection.
