    As we all know, China's quantum communication technology is in the leading position in the
    world.
    In 2016, China's first and the world's first confidential trunk line for quantum communication, the "Beijing-Shanghai Trunk Line", will be opened, with a transmission distance of 2,000 kilometers
    .
    The trunk line was developed and built by Pan Jianwei, academician of the Chinese Academy of Sciences and vice president of the University of Science and Technology of China, and his team, which is of landmark significance
    to the development of quantum communication technology in the world.

    Pan Jianwei and other Chinese scientists started from the development of quantum communication network terminal equipment, low-light detection core devices, network control equipment and other products, for more than 20 years, from tens of kilometers of optical fiber quantum key distribution to free space entanglement photon distribution, from the realization of precise manipulation of single photons to the realization of eight-photon entanglement, marking China's rapid rise
    in the field of quantum communication.

    It is based on the accumulation of these technologies that in 2013, China's quantum secure communication "Beijing-Shanghai trunk line" project was approved by the National Development and Reform Commission
    .
    According to the plan, Beijing, Shanghai, Hefei and Jinan will respectively build metro quantum communication networks, and once the inter-city lines are connected, quantum confidential communication
    with a total length of 2,025 kilometers and 8Gbps between four cities can be realized.

    The construction project of the "Beijing-Shanghai trunk line" mainly includes the construction of the backbone network quantum key distribution system, the construction of a wide-area data transmission network and the construction of a local area network data communication network, passing through Beijing to many cities in Shanghai, carrying the confidential transmission of important information, and after completion, it can fundamentally solve the information security problems
    in the fields of national defense, finance, government affairs, commerce and other fields.
    The "Beijing-Shanghai Trunk Line" has also absorbed some high-tech enterprises to participate, considering the mastery of high-tech technologies and independent innovation of products in terms of participating technology enterprises
    .

    The quantum communication industry is a blue ocean with a vast
    future.
    The Industrial Securities research report pointed out that quantum communication is expected to move towards large-scale applications, and it is expected that the market share will reach hundreds of billions in the next 10 years
