The control of the quantum transport is an issue of current interest for the construction of new devices. In this work, we investigate this possibility in the realm of quantum graphs. The study allows the identification of two distinct periodic quantum effects which are related to quantum complexity, one being the identification of transport inefficiency, and the other the presence of peaks of full transmission inside regions of suppression of transport in some elementary arrangements of graphs. Motivated by the power of quantum graphs, we elaborate on the construction of simple devices, based on microwave and optical fibers networks, and also on quantum dots, nanowires and nanorings. The elementary devices can be used to construct composed structures with important quantum properties, which may be used to manipulate the quantum transport.

量子传输的控制是新装置的构建当前引起关注的问题。在这项工作中，我们研究了量子图领域中的这种可能性。该研究允许识别与量子复杂性有关的两种不同的周期性量子效应，一种是识别传输效率低下，另一种是在图的某些基本排列中在抑制传输的区域内存在完全透射峰。受量子图功能的激励，我们详细介绍了基于微波和光纤网络以及量子点，纳米线和纳米环的简单设备的构造。基本器件可用于构造具有重要量子性质的组成结构，可用于操纵量子传输。
