This paper is an overview of quantum communication and propose the future directions of quantum communication, Quantum communication is a far more efficient technology compared with classical communication greater information storage capacity, higher security provided by quantum key which based on basic quantum mechanics laws and faster transmission speed without the limitation of distance. It is a mainstream of future communication developing direction. This paper depicts the basic architecture of quantum communication from different perspectives such as quantum internet, quantum key distribution and integration of quantum communication with other frontier technology. This gives a brief picture of current development of quantum communication. By integrating previous research, this paper demonstrated several existing challenges in decoherence, scalability of quantum network and verification and certification of information. Then this paper analysis the feasibility of solutions to those problems. Finaly, list the opportunities of quantum communication and its benefits, giving directions of future development like integrate photonic technology and free space quantum communication.
