二体量子态的纠缠不超过其纠缠代价。这个著名的不等式可以被理解为纠缠动力学的第二定律，在纠缠操纵的渐近制度，排除了永久纠缠提取机器的可能性，从有限的储备产生无限的纠缠。在本文中，我建立了一个完善的纠缠动力学第二定律，适用于纠缠操纵的非渐近制度。
The distillable entanglement of a bipartite quantum state does not exceed its entanglement cost. This well known inequality can be understood as a second law of entanglement dynamics in the asymptotic regime of entanglement manipulation, excluding the possibility of perpetual entanglement extraction machines that generate boundless entanglement from a finite reserve. In this paper, I establish a refined second law of entanglement dynamics that holds for the non-asymptotic regime of entanglement manipulation.
