标题： Quantum Information Processing, Sensing and Communications: Their Myths, Realities and Futures

摘要： 最近在量子信息处理、传感和通信方面的进展被综述，目的是识别相关知识空白并制定其未来演进的路线图。 由于量子系统的操作容易受到退相干的有害影响，这表现为比特翻转、相位翻转或两者都有，因此在存在和不存在量子编码的情况下，都回顾了量子误差缓解这一关键主题。 还讨论了量子机器学习的最新进展、知识空白和未来演进，随后探讨了量子雷达系统，并简要推测了在量子领域集成感知和通信的可行性。 最后，我们以一组有前景的未来研究想法结束，这些想法旨在利用经典通信领域的思想，实现最终安全的量子通信。 显示英文摘要

摘要： The recent advances in quantum information processing, sensing and communications are surveyed with the objective of identifying the associated knowledge gaps and formulating a roadmap for their future evolution. Since the operation of quantum systems is prone to the deleterious effects of decoherence, which manifests itself in terms of bit-flips, phase-flips or both, the pivotal subject of quantum error mitigation is reviewed both in the presence and absence of quantum coding. The state-of-the-art, knowledge gaps and future evolution of quantum machine learning are also discussed, followed by a discourse on quantum radar systems and briefly hypothesizing about the feasibility of integrated sensing and communications in the quantum domain. Finally, we conclude with a set of promising future research ideas in the field of ultimately secure quantum communications with the objective of harnessing ideas from the classical communications field.
