Russian Federation and China protested a 3800 km communication channel that can neither listen nor break

Russia and China exchanged pictures of 256 × 64 pixels using a satellite and quantum key encryption 310 Kbps. Russian scientists from the University of Mrs. , Russian quantum center and Kuspeis Technology, have published material in the scientific edition of Optics Express, where they claim that they managed to implement a safe satellite channel of 3800 km. It is impossible to intercept the data transmitted by this channel, reports NPLUS1.

In the article, the authors report that they initially transferred a quantum key to 310 kbps between stations in Zvenigorod (RF) and Nanshan (China), and then the stations exchanged messages that scientists were characterized as completely protected from interception. Messages contained an image of 256 × 64 pixels. The satellite bond was provided by the Chinese Mo-Tzu apparatus, launched in 2016 to transmit distributed quantum keys using laser channels.

The transmission of messages by the satellite quantum channel has become possible thanks to two telescopes. The first was used to work with information and the second to be sustained. The Russians hope that Chinese partners will help them develop protected networks for data transmission. In 2022, China launched the Jinan 1 quantum satellite ("Jinan-1"). It is able to pass quantum secure keys in 2 or even 3 times faster than a somewhat outdated "mo-tzu".
