Quantum electronics has significantly evolved over the last decades. Where initially the clear focus was on light-matter interactions, nowadays approaches based on the electron's wave nature have solidified themselves as additional focus areas. This development is largely driven by continuous advances in electron quantum optics, electron based quantum information processing, electronic materials, and nanoelectronic devices and systems. The pace of research in all of these areas is astonishing and is accompanied by substantial theoretical and experimental advancements. What is particularly exciting is the fact that the computational methods, together with broadly available large-scale computing resources, have matured to such a degree so as to be essential enabling technologies themselves. These methods allow to predict, analyze, and design not only individual physical processes but also entire devices and systems, which would otherwise be very challenging or sometimes even out of reach with conventional experimental capabilities. This review is thus a testament to the increasingly towering importance of computational methods for advancing the expanding field of quantum electronics. To that end, computational aspects of a representative selection of recent research in quantum electronics are highlighted where a major focus is on the electron's wave nature. By categorizing the research into concrete technological applications, researchers and engineers will be able to use this review as a source for inspiration regarding problem-specific computational methods.
在过去几十年中，量子电子学有了显著发展。最初，其明确重点是光与物质的相互作用，而如今基于电子波动性的方法已稳固地成为了额外的重点领域。这一发展很大程度上是由电子量子光学、基于电子的量子信息处理、电子材料以及纳米电子器件和系统的不断进步所推动的。所有这些领域的研究步伐令人惊讶，并且伴随着大量的理论和实验进展。特别令人兴奋的是，计算方法与广泛可用的大规模计算资源已经成熟到如此程度，以至于它们本身成为了必不可少的使能技术。这些方法不仅能够预测、分析和设计单个物理过程，还能设计整个器件和系统，否则用传统实验能力来做这些将极具挑战性，甚至有时根本无法实现。因此，这篇综述证明了计算方法对于推动不断扩展的量子电子学领域的重要性日益凸显。为此，本文突出了量子电子学近期代表性研究中的计算方面，主要关注电子的波动性。通过将研究分类到具体的技术应用中，研究人员和工程师将能够把这篇综述用作针对特定问题的计算方法的灵感来源。
