Quantum information science and technology enables informational secure quantum cryptography (quantum communication). This presentation will highlight a few of our progress towards the ultimate goal of global quantum communication. We have established a trustful-relay based Backbone connecting Beijing to Shanghai passing through Jinan and Hefei, four metropolitan networks, over 2000-km fiber links. Currently real-world applications by banks, securities and insurance companies are on trial. Another complementing route is to attain global quantum communication based on satellite. We have spent the past decade in performing systematic ground tests for satellite-based quantum communications. Our efforts finally ensure a successful launch of the Micius satellite. Future Prospects include building a global quantum communication infrastructure with satellite and fiber networks, enormous spatial resolution and global precise timing information sharing networks with applications for the global quantum communication network, ultra-precise optical clocks in outer space to detect gravitational wave signal with lower frequency, and Bell-test experiment with human-observer at a distance on the order of one light-second.
