量子熵和四粒子纠缠的强次可加性不等式

Strong subadditivity inequality for quantum entropies and four-particle entanglement

Asoka Biswas, G. S. Agarwal

摘要:

三粒子复合系统的强次可加性不等式是量子信息理论中的一个重要不等式,可以通过四粒子纠缠态来研究。利用$Λ$组态的两个三能级原子与双模腔场相互作用,利用Raman绝热通过技术制备了四粒子纠缠态。利用这种四粒子纠缠,我们研究了第一次强次加性不等式的各个方面。

英文摘要:

Strong subadditivity inequality for a three-particle composite system is an important inequality in quantum information theory which can be studied via a four-particle entangled state. We use two three-level atoms in $Λ$ configuration interacting with a two-mode cavity and the Raman adiabatic passage technique for the production of the four-particle entangled state. Using this four-particle entanglement, we study for the first time various aspects of the strong subadditivity inequality.
