We determine the semantic security capacity for quantum wiretap channels. We extend methods for classical channels to quantum channels to demonstrate that a strongly secure code guarantees a semantically secure code with the same secrecy rate. Furthermore, we show how to transform a non-secure code into a semantically secure code by means of biregular irreducible functions (BRI functions). We analyze semantic security for classical quantum channels and for quantum channels.

量子窃听通道的语义安全

我们确定了量子窃听通道的语义安全能力。我们将经典通道的方法扩展到量子通道，以证明强安全代码可以保证具有相同保密率的语义安全代码。此外，我们展示了如何通过双正则不可约函数（BRI 函数）将非安全代码转换为语义安全代码。我们分析了经典量子通道和量子通道的语义安全性。
