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 for M ≤ 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 than M = 4 symbols.

我们对量子接收器和调制方法进行了系统研究，以实现资源高效的量子增强光通信。我们引入了量子启发的调制方案，理论上比传统协议产生更好的资源效率。 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器测试台证明了M ≤ 16 个传统和受量子启发的通信字母表的散粒噪声限制符号错误率。此外，我们通过实验验证了我们的量子启发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 个符号的通信字母的能量和带宽的组合使用。
