Quantum imaging is a multifaceted field of research that promises highly efficient imaging in extreme spectral ranges as well as ultralow‐light microscopy. Since the first proof‐of‐concept experiments over 30 years ago, the field has evolved from highly fascinating academic research to the verge of demonstrating practical technological enhancements in imaging and microscopy. Here, the aim is to give researchers from outside the quantum optical community, in particular those applying imaging technology, an overview of several promising quantum imaging approaches and evaluate both the quantum benefit and the prospects for practical usage in the near future. Several use case scenarios are discussed and a careful analysis of related technology requirements and necessary developments toward practical and commercial application is provided.

量子成像的应用前景

量子成像是一个多方面的研究领域，它有望在极端光谱范围以及超低光显微镜下实现高效成像。自30年前进行首次概念验证实验以来，该领域已经从引人入胜的学术研究发展到了在成像和显微镜技术方面展示出实用的技术增强优势。在这里，目的是为量子光学界以外的研究人员，特别是那些应用成像技术的研究人员，概述几种有前途的量子成像方法，并评估量子收益和在不久的将来的实际应用前景。讨论了几种用例场景，并提供了对相关技术要求的认真分析以及对实际和商业应用的必要发展。
