AI 中文摘要
受量子姆潘巴效应相关最新发现的驱动，开放量子系统的反常弛豫动力学备受关注。虽然加速热化到平衡已被广泛研究，但动态加速向非平衡稳态的收敛仍是巨大挑战。本文发现一个瞬态工程非互易耗散通道可为双模式模型和初始态提供加速收敛到目标互易非平衡稳态的捷径。利用相互作用的玻色子模式证明，非互易通道的时间激活有效抑制了长时间的模式间能量振荡，实现向环境的快速单向热倾倒。结果表明这种弛豫加速是稳健的且与非互易方向无关。为连续变量量子系统中的快速态制备和冷却提供了有力的热力学技术，对低温量子信息处理尤为关键。
英文摘要
Driven by recent discoveries regarding the quantum Mpemba effect, the anomalous relaxation dynamics of open quantum systems have garnered significant attention. While expediting thermalization to equilibrium has been extensively studied, dynamically accelerating the convergence toward nonequilibrium steady states remains a formidable challenge. In this article, we find a transient engineered nonreciprocal dissipative channel can provide a shortcut that accelerates convergence to the target reciprocal nonequilibrium steady state for the considered two-mode model and initial states. Using interacting bosonic modes, we demonstrate that the temporal activation of a nonreciprocal channel efficiently suppresses prolonged inter-mode energy oscillations, enforcing a rapid, unidirectional thermal dump into the environment. Counterintuitively, we find that this relaxation speedup is robust and independent of the direction of the nonreciprocity. Our results provide a powerful thermodynamic technique for rapid state preparation and cooling in continuous-variable quantum systems, particularly critical for low-temperature quantum information processing.
