Robustness of deformed catlike states under dissipative decoherence

The generation of coherent superposition of distinct physical systems and the construction of robust entangled states under decoherence are the most experimental challenges of quantum technologies. In a recent work [1], we have investigated the behaviors of catlike states of a deformed harmonic oscillator under dissipative decoherence. Varying the deformation parameters, we have obtained catlike states having more resistance against decoherence than catlike states of the ordinary harmonic oscillator. Furthermore, we have studied nonclassical properties and entanglement of different catlike states subjects to decoherence caused by a dissipative interaction with a large environment. Depending on different parameters of deformation, we have shown that the nonclassical properties of catlike states under dissipative interaction can be more retarded and preserved in the time [1].
