本研究采用级联开放量子系统形式，克服了先前Lindblad主方程的不一致性，实现了与互易系统相比十六倍的稳态非互易能量优势，并揭示了依赖于耗散的电池到充电器效率，为高性能量子能量存储奠定了严谨基础。
AI 中文摘要
非互易量子电池利用储层工程实现受控能量转移，预示着量子能量存储的范式转变。先前一项利用Metelmann-Clerk形式的研究报告称，与互易对应物相比，非互易能量积累增强了四倍。然而，这种四倍增强似乎源于一个表现出根本不一致性的Lindblad主方程，该方程可能系统地低估了实际的非互易优势。我们的方法植根于严格建立的级联开放量子系统形式，该形式确保了数学一致性和物理保真度。值得注意的是，我们超越了先前报告的四倍基准，实现了与互易系统相比与体制无关的十六倍稳态非互易能量优势。我们进一步发现了一种依赖于耗散的电池到充电器效率，在对称阻尼下为四倍，当电池耗散较小时超过该基准，否则低于该基准。这项工作将级联形式确立为高性能量子能量存储的数学严谨且实验可行的基础。
英文摘要
Nonreciprocal quantum batteries harness reservoir engineering for controlled energy transfer, heralding a paradigm shift for quantum energy storage. A prior study utilizing the Metelmann-Clerk formalism reported a fourfold enhancement in nonreciprocal energy accumulation over reciprocal counterparts. This fourfold enhancement, however, appears to stem from a Lindblad master equation that exhibits fundamental inconsistencies, which may systematically understate the actual nonreciprocal advantage. Our approach is rooted in the rigorously established cascaded open quantum systems formalism, which ensures both mathematical consistency and physical fidelity. Remarkably, we surpass the previously reported fourfold benchmark, attaining a regime-independent sixteenfold steady-state nonreciprocal energy advantage over reciprocal systems. We further uncover a dissipation-dependent battery-to-charger efficiency, fourfold under symmetric damping, surpassing this benchmark when the battery is less dissipative, and lower otherwise. This work establishes the cascaded formalism as a mathematically rigorous and experimentally viable foundation for high-performance quantum energy storage.
