论文摘要
从量子系统中提取工作是量子热力学的重要领域之一。作为重要的热力学量,麦角拷贝差距表征了全球和局部最大提取作品之间的差异。我们根据$ d \ times d \ times d $ tripartite可分离状态得出了麦角缝间隙的分析上限。该界限还为三方状态的可分离性提供了必要的标准。列出了详细的示例,以说明此可分离性标准的效率。
Extracting work from quantum system is one of the important areas in quantum thermodynamics. As a significant thermodynamic quantity, the ergotropy gap characterizes the difference between the global and local maximum extractable works. We derive an analytical upper bound of the ergotropic gap with respect to $d\times d\times d$ tripartite separable states. This bound also provides a necessary criterion for the separability of tripartite states. Detailed examples are presented to illustrate the efficiency of this separability criterion.
