动态资源

Dynamical Resources

Gilad Gour, Carlo Maria Scandolo

摘要:

量子信道是量子信息的精髓,被用于所有协议,并描述系统如何在空间和时间上进化。因此,它们在量子资源的操纵中起着关键作用,它们本身往往是资源,称为动态资源。这迫使我们超越量子态的标准资源理论。在这里,我们提供了一个严格的基础动力资源理论,其中发挥作用的资源是量子信道,解释如何操纵动态资源与自由的超级信道。特别地,当自由超信道的集合是凸的时,我们提出了一种新的凸资源单调的无限完备族的构造,给出了自由超信道下可转换的充要条件.在证明了凸动态资源理论中的转换问题可以用圆锥线性规划来解决之后,我们定义了各种动态资源的资源理论协议。这些结果作为框架的具体例子的研究理论的动力资源,如动力纠缠理论。

英文摘要:

Quantum channels are quintessential to quantum information, being used in all protocols, and describing how systems evolve in space and time. As such, they play a key role in the manipulation of quantum resources, and they are often resources themselves, called dynamical resources. This forces us to go beyond standard resource theories of quantum states. Here we provide a rigorous foundation for dynamical resource theories, where the resources into play are quantum channels, explaining how to manipulate dynamical resources with free superchannels. In particular, when the set of free superchannels is convex, we present a novel construction of an infinite and complete family of convex resource monotones, giving necessary and sufficient conditions for convertibility under free superchannels. After showing that the conversion problem in convex dynamical resource theories can be solved with conic linear programming, we define various resource-theoretic protocols for dynamical resources. These results serve as the framework for the study of concrete examples of theories of dynamical resources, such as dynamical entanglement theory.
