我们提出了一个系统的研究量子接收机和调制方法,使资源有效的量子增强光通信。我们引入量子启发的调制方案,理论上产生更好的资源效率比传统协议。在实验上,我们使用软件可配置的光通信时间分辨量子接收机测试平台,证明了M ≤ 16传统和量子启发通信字母表的散粒噪声极限符号错误率。此外,我们通过实验验证了我们的量子调制方案提高了实际量子测量的准确性,并显着优化了长于M = 4个符号的通信字母表的能量和带宽的组合使用。
We present a systematic study of quantum receivers and modulation methods enabling resource efficient quantum-enhanced optical communication. We introduce quantum-inspired modulation schemes that theoretically yield a better resource efficiency than legacy protocols. Experimentally, we demonstrate below the shot-noise limit symbol error rates forM≤ 16 legacy and quantum-inspired communication alphabets using software-configurable optical communication time-resolving quantum receiver testbed. Further, we experimentally verify that our quantum-inspired modulation schemes boost the accuracy of practical quantum measurements and significantly optimize the combined use of energy and bandwidth for communication alphabets that are longer thanM= 4 symbols.
