给出了一个基本熵数据处理不等式的量子形式。它建立了可以在散射过程的输出通道中生成的熵的下限,该散射过程涉及独立输入玻色子模式的集合(例如,电磁场的模式)。这个不等式在量子信息理论中的影响可能很大,并在这项工作中考虑了一些相关的影响。
The quantum version of a fundamental entropic data-processing inequality is presented. It establishes a lower bound for the entropy that can be generated in the output channels of a scattering process, which involves a collection of independent input bosonic modes (e.g., the modes of the electromagnetic field). The impact of this inequality in quantum information theory is potentially large and some relevant implications are considered in this work.
