• Abstract: We study the quantum properties of light propagating through an array of coupled nonlinear waveguides and forming a discrete soliton. We demonstrate that it is possible to use certain types of quasi-solitons to form continuous variables entanglement between the certain pair of waveguides. This entanglement generation process occurs even with a very large number of photons in the laser field used, so it does not require a special material with an extremely high nonlinearity coefficient. Also absorption in the waveguide media does not influence it too much.

  We study single-photon induced electromagnetically induced transparency (EIT) in many-emitter waveguide quantum electrodynamics (wQED) We find that the nonlinear dispersion results in the appearance of a side peak for frequencies smaller than the resonant EIT frequency which turns into a pronounced plateau as the nonlinearity is enhanced. Long-distance quantum networking aided with quantum memories can serve as one of the targeted applications of this work.
