China is set to start construction on a quantum communication line between Wuhan, capital of Hubei province, and Hefei, the capital of Anhui province, state-owned newspaper China Daily reported last week.
The 300-kilometer ultra-high security line is planned to start operating around the end of next year, bringing China a step closer to having the world's most secure communication network.
It will link with the 2,000-kilometer Beijing-Shanghai quantum communication network which is expected to be completed at the end of this year, according to a statement from China Aerospace Science and Industry Corporation (CASIC).
The Wuhan-Hefei line will initially be used by government bodies and financial institutions in Wuhan before being opened to the business sector and extended to cities along the line, explained Wu Xiaofeng, a senior manager at CASIC who is overseeing the project.
Wu told China Daily that the line involves an initial investment of about CNY200m ($29m) and all of its technologies and equipment will be developed by Chinese scientists.
CASIC develops advanced laser technologies and instruments, which are key components of a quantum communication network, the newspaper noted.
It is theoretically impossible to wiretap, intercept or crack the information transmitted through quantum communication lines.
All major technology powers around the world, including the United States, the European Union and Japan, are investing in the research of quantum encryption technologies, China Daily said.
In August, China launched the world's first quantum experiment satellite to verify quantum communication theories.
