论文摘要
我们研究以确定性的方式随时间变化的量子通道，即它们以独立但不相同的方式变化。我们为经典的纠缠辅助和无助的能力提供了编码定理。然后，我们将理论专门用于有损的骨量子通道，并显示了对比鲜明的示例的存在，在这些示例中，能力可以或从有损参数的限制行为中得出。
We study quantum channels that vary on time in a deterministic way, that is, they change in an independent but not identical way from one to another use. We derive coding theorems for the classical entanglement assisted and unassisted capacities. We then specialize the theory to lossy bosonic quantum channels and show the existence of contrasting examples where capacities can or cannot be drawn from the limiting behavior of the lossy parameter.
