Creation of entanglement of continuous variables using small Kerr nonlinearity
S. Ya. Kilin, Alexander B. Mikhalychev · Optics and Spectroscopy · 2010
The protocol for creating entangled states of electromagnetic field modes at a distance of 100 km using a small Kerr nonlinearity (χ min ≈ 0.01) is proposed. This technique corresponds to the modern level of experimental equipment and can be used for practical purposes, such as quantum key distribution.
