Mozi is the world’s first quantum scientific experimental satellite developed by China. It is named after Mozi who first proposed that light travels in a straight line and designed the first small hole imaging experiment. Mozi laid the foundation for optical communication and quantum communication, therefore the satellite was named after him.
On August 16, 2016, a Long-March II-D rocket launched the Mozi satellite successfully at the Jiuquan Satellite Launch Center. After the Mozi Quantum Satellite entered into its orbit, it conducted an on-orbit test for about three months and then it entered into operation.
The quantum satellite project was started in December 2011, and breakthroughs were made on a series of key technologies, including high-precision tracking, satellite-ground polarization state preservation, mismatch correction, and satellite-borne quantum entanglement.
The successful launch of Mozi helps establish a confidential satellite-ground quantum communication and a scientific experiment system.
