Global quantum communication with satellite

Principal investigator
Introduction

Develop and finally build a world-wide quantum secure communication network on the basis of the established long distances free-space quantum communication platform between the ground and the satellite. As the quantum signal can be easily affected by the environment, we try to establish a quantum communication system that can overcome the noise from the daylight, so that it can run for the whole day besides in the night when the noise is low. Quantum communication experiment under the water is also carried out to expand the free-space-link to the water-link. To have a more stable quantum communication system, brighter quantum entanglement sources are explored. The fundamentals of quantum mechanics will be verified across large distances using the free-space quantum communication platform between the ground and the satellite.
