Generation of entangled states by a nonlinear coupler pumped in one mode induced by broadband laser

摘要: Kerr nonlinear coupler consists of two oscillations in which one them linearly excited by an external classical field. This is assumed to be decomposed into parts: a coherent part and randomly fluctuating chaotic component that δ-correlated, Gaussian, Markov, stationary process (white noise). We solve set coupled stochastic integro-differential equations involved the problem with all initial conditions obtain analytical formulae for complex probability amplitudes finite n-photon Fock states. Especially, our study shows system also able generate maximally entangled states and, as consequence, discussed behaves two-qubit results compared those derived previously literature.
