Chinese satellites pass encryption can not be cracked

China first successfully tested the transmission of quantum data between satellites and the ground.

China in a paper published today in the journal Nature. The satellite has successfully carried out quantum coding of two terrestrial stations in China at 645km and 1,200km, according to Reuters.

Quantum chips are considered to be the most secure signal today and there is no technology to intervene and decipher this type of signal. Pan Jianwei, a research scientist conducting experiments at the Chinese Academy of Sciences, said the data transfer was more efficient through optical fibers 20 times.

Quantum communications are capable of super-high security because quantum photons can not be split or cloned. Therefore, it can not be eavesdropped, tampered with or intercepted information transmitted through the system.

According to Xinhua, any interference or eavesdropping would create disturbances on the quantum channel, change the quantum state, and destroy information. "This method of communication can meet the requirements of an absolute secure telephone or large data transmission , " Pan said of the prospective technology used in finance and defense.

China launches the world's first quantum satellite in August 2016 to establish an eavesdropping communications channel. The satellite will ensure communications between Beijing and Urumqi, the capital of the autonomous region. Xinjiang, western China.

China insists its space programs are for peaceful purposes, but defense officials in Washington have expressed concern over Beijing's growing space power and water capacity. This uses devices in space against "rivals" in the event of a conflict.
