Oscillating between classically entangled state and separable state: an analogy between classical and quantum optics
Shahram Dehdashti, Firat Yasar · Journal of the Optical Society of America B · 2020
In this paper, we study the possible realization of a classical system with quantum characteristics on the level of classical optics. Indeed, following Arrizon et al. [ J. Opt. Soc. Am. A 32 , 1140 ( 2015 ) JOAOD6 0740-3232 10.1364/JOSAA.32.001140 ], we first use quantum optics formalism to consider the propagation of two coherent states in a Kerr medium where the interaction between the two states is described by the cross-Kerr interaction. We then draw an analogy between the dynamical process of this structure and that of a Gaussian wave propagating in a quadratic gradient index medium. We demonstrate that by using this structure, we can generate a state that oscillates between a classically entangled state and a separable one.
