主 题:Quantum State Ordering Driven by Quantum Battery Capacity and Correlation
报告人:李波 浙大城市学院教授
摘 要:The rapid advancements in quantum information science and quantum thermodynamics have led to increasingly interdisciplinary innovations. One notable development is the concept of the ergotropic gap, defined as the difference between global and local ergotropy. Building on this foundation, multipartite ergotropic gap indicators have been proposed to enhance methods of entanglement classification [Phys. Rev. A 109, 062427 (2024)]. Motivated by this perspective, the thermodynamic notion of quantum battery capacity—closely related to ergotropy and defined as the energy difference between maximally and minimally achievable states under unitary evolution—is examined to address state ordering problems. The investigation focuses on comparing state orderings using three measures: battery capacity, entanglement of formation, and quantum discord, with particular emphasis on two-qubit Bell-diagonal states. Remarkably, certain classes of these states exhibit identical ordering patterns across all three measures under specific conditions.
