Quantum communication uses subatomic particles such as photons－the individual particles of light－to send data using quantum mechanics, said Nie Jiming, a quantum researcher at the CAS.
This communication is regarded as the most secure because these particles cannot be destroyed or duplicated and can detect eavesdroppers and alert authorities, he added.
"It will have great application in defense, finance, energy and other fields where security is paramount," he said.
In 2009, military officials used a quantum communication hotline to orchestrate the military parade for the 60th anniversary of the founding of the People's Republic of 皇冠体育app.
In 2015, the Industrial and Commercial Bank of 皇冠体育app used a quantum network to transmit data within Beijing, becoming the first Chinese bank to use the technology.
Given its potential, many countries, including the United States, Japan and the United Kingdom, are also racing toward quantum communication supremacy, but "I believe 皇冠体育app will still lead the race in the next five years," said Pan.
