China will launch its first satellite ofquantum science experiment in July, which is also the first one of the samefield in the world. It will build a network connecting the earth and space byquantum communication. Being different from that before in communication, thenew one will be a breakthrough. Its success in the future will enjoy an honorthat our communication will be safer.
The safety is based on the principles of quantum physics that singlephoton cannot be divided and quantum states cannot be copied. In other words,the information cannot be wiretapped and cannot be cracked, which guarantees thesafety of users.
Meanwhile, China is building its network of quantum communication in bigcities. The project of network equipped with the facility of quantumcommunication from Beijing to Shanghai will be completed in the second halfthis year. It means that China will have a further step in communication.
The new era of communication is coming soon.
