  Quantum computing is a cutting-edge field of information technology that
harnesses the principles of quantum mechanics to perform computations. It has
major implications for the cyber security industry. Existing cyber protection
applications are working well, but there are still challenges and
vulnerabilities in computer networks. Sometimes data and privacy are also
compromised. These complications lead to research questions asking what kind of
cyber protection applications of quantum computing are there and what potential
methods or techniques can be used for cyber protection? These questions will
reveal how much power quantum computing has and to what extent it can
outperform the conventional computing systems. This scoping review was
conducted by considering 815 papers. It showed the possibilities that can be
achievedif quantum technologies are implemented in cyber environments. This
scoping review discusses various domains such as algorithms and applications,
bioinformatics, cloud and edge computing, the organization of complex systems,
application areas focused on security and threats, and the broader quantum
computing ecosystem. In each of these areas, there is significant scope for
quantum computing to be implemented and to revolutionize the working
environment. Numerous quantum computing applications for cyber protection and a
number of techniques to protect our data and privacy were identified. The
results are not limited to network security but also include data security.
This paper also discusses societal aspects, e.g., the applications of quantum
computing in the social sciences. This scoping review discusses how to enhance
the efficiency and security of quantum computing in various cyber security
domains. Additionally, it encourages the reader to think about what kind of
techniques and methods can be deployed to secure the cyber world.
