The rapid development of quantum computing and cryptography unleash the thinking of an internet network that is based on quantum mechanics. The quantum-based internet is predicted to be more secure than the classical one due to its entanglement distribution strategy. The main challenge that can face the quantum internet is the nature of quantum bits which require special circumstances to stay stable. Quantum bit entanglement is fragile and decoherence which leads to missing the entangled photons and disconnection of communication. Recently, different solutions have been suggested to overcome this challenge which are mainly counting on the technologies and materials that can increase the photon lifetime and enhance the ability to transfer it over long distances without losses. In this paper a general overview of this new and interesting research topic is presented which can be considered as an onset for the researchers who are interested in this promising field.
