论文摘要
量子技术的最大实验性挑战是不同物理系统的相干叠加以及在腐蚀性下的稳健纠缠状态的建造。在这项工作中,我们研究了在耗散性的反应下,变形的谐波振荡器的cat状状态的行为。改变变形参数,我们获得了比普通谐波振荡器的cat式状态具有更大抵抗力的cat状状态。此外,我们研究了不同的cat式状态的非古典特性和纠缠,这些状态受到与大环境的耗散相互作用引起的反应性。根据不同的变形参数,我们揭示了在耗散相互作用下的非分类性能可以在当时更弱智和保存。
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 this work, we investigate the behaviors of catlike states of a deformed harmonic oscillator under dissipative decoherence. Varying the deformation parameters, we obtain catlike states having more resistance against decoherence than catlike states of the ordinary harmonic oscillator. Furthermore, we study nonclassical properties and entanglement of different catlike states subjects to decoherence caused by a dissipative interaction with a large environment. Depending on different deformation parameters, we reveal that the nonclassical properties of catlike states under dissipative interaction can be more retarded and preserved in the time.
