来自学术界和工业界的一些最有影响力的参与者最近表达了对量子工程应用的具体兴趣，特别是对控制和处理进入凝聚态的量子信号的新概念。当操纵表现为物质波的粒子束时，一个重要的操作涉及相对于它们自身的能量进行过滤;这样的目标可以通过嵌入到合适背景中的特定尺寸和纹理的单个平面内含物来很好地服务。大量的夹杂物/主机组合从现实的材料进行了尝试和最佳尖锐的共振制度，这对应于这样一个简单的结构的性能限制，仔细确定。这些结果可能会激发人们努力推广所采用的方法和翻译的复杂的逆向设计技术，已经成功地实现了纳米光子设置，到量子竞技场。
Some of the most influential players from academia and industry have recently expressed concrete interest for quantum engineering applications, especially for new concepts in controlling and processing the quantum signals traveling into condensed matter. An important operation when manipulating particle beams behaving as matter waves concerns filtering with respect to their own energy; such an objective can be well-served by a single planar inclusion of specific size and texture embedded into suitable background. A large number of inclusion/host combinations from realistic materials are tried and the optimally sharp resonance regimes, which correspond to performance limits for such a simplistic structure, are carefully identified. These results may inspire efforts towards the generalization of the adopted approach and the translation of sophisticated inverse design techniques, already successfully implemented for nanophotonic setups, into quantum arena.
