在稳定的非平衡态中抑制相干能量回流同时保持可提取能量，仍是量子能量存储的核心挑战。本文引入一种 reservoir-engineered 双充电器量子电池架构，利用非平衡耗散作为控制资源来稳定有用的存储能量：与热库耦合的驱动源提供激发，与冷库耦合的缓存将共振三体跃迁偏向充电方向，并抑制导致能量回流的缀饰态相干性。该机制建立具有有限功熵的粒子数反转稳态，将可逆充电器-电池交换转化为持续能量存储。对于等间距多能级电池，存储能量和功熵随可访问能级数量近似线性缩放，存储能量利用率趋近于1；伴随的稳态热流为充电机制提供热力学特征。研究表明，耗散工程是实现超越瞬态相干充电协议的稳定可扩展量子能量存储的策略。
英文摘要
Suppressing coherent energy backflow while maintaining extractable energy in a stable nonequilibrium state remains a central challenge for quantum energy storage. Here, we introduce a reservoir-engineered dual-charger quantum battery architecture, in which nonequilibrium dissipation is exploited as a control resource to stabilize useful stored energy. A hot-reservoir-coupled driver supplies excitations, while a cold-reservoir-coupled cache biases the resonant three-body transition toward charging and suppresses the dressed-state coherences responsible for energy backflow. This mechanism establishes a population-inverted steady state with finite ergotropy and converts reversible charger--battery exchange into persistent energy storage. For uniformly spaced multilevel batteries, we show that the stored energy and ergotropy scale approximately linearly with the number of accessible levels, while the stored-energy utilization approaches unity. The accompanying stationary heat current provides a thermodynamic signature of the charging regime. Our results demonstrate dissipation engineering as a strategy for achieving stable and scalable quantum energy storage beyond transient coherent charging protocols.
