我國研發的全球首個量子衛星即將發射

The first quantum communications satellite developed by China is expected to launch in July of this year. The Beijing–Shanghai quantum private communications line will also be opened in the second half of this year, according to Pan Jianwei, academic at the Chinese Academy of Sciences, during an interview with China Youth Daily.

由中國研發的全球第一顆量子通訊衛星將於今年七月發射。據中科院院士潘建偉在接受《中國青年報》的一次採訪中透露，從北京到上海的量子保密通訊線路也將於今年下半年開通。

According to Pan, this milestone means that a quantum communications network will be formed, and that 30 years of research on quantum information will be finally put to use. Pan said that quantum communication between the satellite and the ground will be achieved for the first time anywhere in the world.

據潘建偉院士透露，這一里程碑式的成功意味着中國將建立一個量子通訊網絡，對於量子信息長達三十年的研究終將投入使用。潘院士表示，中國將在全球首次實現衛星和地面基站的量子通訊。

In recent years, quantum communications is considered to be supportive research for next-generation communication technology because of its transmission efficiency and absolute security. Pan said that, as quantum technology is indivisible and cannot be cloned, it may be implemented as an information carrier for the distribution of sensitive information, thereby guaranteeing the secure transmission of important content. Quantum communications research has become a focus and frontier of global research in physics.

近年來，由於在傳輸效率和信息安全上具有顯著的優勢，量子通訊手段被認爲是次世代通訊技術的基礎。據潘院士透露，由於量子既不能被分割，也不能被複制，因此可以用來作爲敏感信息的傳播載體，從而保障從要信息的傳輸安全。量子通訊研究已經成爲物理學界一個關注焦點和前沿性課題。

China started developing its quantum satellite in 2011, and launched the quantum optical fiber communication network project, the Beijing–Shanghai line, in 2013. The Beijing–Shanghai quantum private communications line will cover a total length of over 2,000 kilometers, connecting a network of numerous cities including Beijing, Jinan, Hefei and Shanghai. It will be the world's first wide-area optic fiber quantum private network.

中國在2011年開始研發量子衛星，並於2013年開始了量子光纖通訊網絡（北京-上海段）項目。從北京到上海的這條量子保密通訊線路總長達到了2000公里，連接了包括北京、濟南、合肥和上海在內的許多城市的網絡。這將是全球第一個廣域光纖量子保密網絡。

According to Pan, the assembly of the quantum satellite has already been completed. The satellite has passed electrical measurement and thermal balance testing, and is currently undergoing mechanical and magnetic testing in Shanghai's Small Satellite Engineering Center.

據潘院士透露，量子通訊衛星的裝配工作已經完成了。這顆衛星已經通過了電測試和熱平衡測試，目前正在上海的小衛星工程中心進行機械和磁力檢測。

"With further development, quantum communications should benefit millions of households in the near future," Pan said, adding: "I hope that within another 10 years of hard work, online transfers and payments can be guaranteed through quantum communication for every consumer."

潘院士表示：“隨着進一步的發展，量子通訊將在不遠的將來使數以百萬計的家庭受益。我希望在十年之內，通過我們的艱苦奮鬥，量子通訊可以保障每一個消費者的在線信息傳輸和在線支付的安全。”
