  Owing to its outstanding parallel computing capabilities, quantum computing
(QC) has been a subject of continuous attention. With the gradual maturation of
QC platforms, it has increasingly played a significant role in various fields
such as transportation, pharmaceuticals, and industrial manufacturing,achieving
unprecedented milestones. In modern society, wireless communication stands as
an indispensable infrastructure, with its essence lying in optimization.
Although artificial intelligence (AI) algorithms such as Reinforcement Learning
(RL) and mathematical optimization have greatly enhanced the performance of
wireless communication, the rapid attainment of optimal solutions for wireless
communication problems remains an unresolved challenge. QC, however, presents a
new alternative. This paper aims to elucidate the fundamentals of QC and
explore its applications in wireless communications and networking. First, we
will provide a tutorial on QC, covering its basics, characteristics, and
popular QC algorithms. Next, we will introduce the applications of QC in
communication and networking, followed by its applications in miscellaneous
areas such as security and privacy, localization and tracking, and video
streaming. Finally,we will discuss remaining open issues before concluding.
