将感知与通信功能集成于同一系统是下一代网络的重要创新驱动力。本文提出一种量子集成感知与通信（QISAC）协议，利用信息载体中的量子纠缠实现超密集编码与量子感知。该方法通过变分电路学习自适应优化编码与量子测量，并采用基于经典机器学习的解码器与估计算法处理测量结果。数值实验表明，在四维量子系统（qudit）中，所提QISAC协议可在经典通信速率与参数估计精度之间实现灵活权衡。
原文摘要 · Abstract (English)
The integration of sensing and communication functionalities within a common system is one of the main innovation drivers for next-generation networks. In this paper, we introduce a quantum integrated sensing and communication (QISAC) protocol that leverages entanglement in quantum carriers of information to enable both superdense coding and quantum sensing. The proposed approach adaptively optimizes encoding and quantum measurement via variational circuit learning, while employing classical machine learning-based decoders and estimators to process the measurement outcomes. Numerical results for qudit systems demonstrate that the proposed QISAC protocol can achieve a flexible trade-off between classical communication rate and accuracy of parameter estimation.
