Based on the extended Huygens–Fresnel principle, we study the propagation properties of partially coherent double-vortex beams in turbulent atmosphere. The intensity distribution of the beams on propa...
Cross-Kerr nonlinearity between continuous-mode coherent states and single photons
Cross-Kerr nonlinearity continuous-mode coherent states single photons
2013/7/3
Weak cross-Kerr nonlinearities between single photons and coherent states are the basis for many applications in quantum-information processing. These nonlinearities have so far mainly been discussed ...
