Abstract: The quantum information science is a new branch of physics which uses quantum states to carry information， and uses quantum mechanics to transmit and compute information. The quantum information technology can accomplish tasks that classical information technology can not accomplish. The quantum information science includes quantum communication and quantum computing. The quantum communication has entered the industry，and quantum computing also comes out of laboratories. The emerging quantum information industry will lead the next information revolution，and can provide more employment opportunities for graduates from physics.

Key words: quantum information, quantum communication, quantum computing
