Quantum Internet: Functionalities, Protocols and Applications

In the recent years, and with the rapid development in the field of Quantum Internet (QI) and its applications, and as a result of this development, researchers showed the difference between the traditional internet and the QI. The present study discusses more about the concept of the QI, especially the functionalities, protocols, and applications of QI. This study gives researchers and readers a deeper knowledge about the QI in general and its applications in particular, and how these applications have helped the QI to be better than the current internet in the coming years through more secure and provide a high and optimizations of performance, more reliability, high speed when implementing, and fewer errors.
