Chinese scientists invented a quantum internet that cannot be broken

< IMG SRC = "/Uploads/Blogs/E4/95/IB-FQJ05QE4l_316240df.jpg" Alt = "Chinese scientists invented a quantum internet that cannot be broken"/> ~ < P > Scientists from China have reached a revolutionary breakthrough in the field of quantum securely protected straight lines & rsquo; qsdc), providing unprecedented speed and data range. New technology uses quantum photons to transmit information, which makes it virtually invulnerable to intercepting & mdash; Any third-party intervention instantly changes the quantum state of the signal and immediately fixed.

< P > During experimental tests, researchers managed to reach a speed of 2.38 kbps at a distance of 104.8 km at a standard fiber optic cable. This result significantly exceeds the previous world record of 2022, which was only 0.54 bits per 100 km. At a shorter distance of 50.3 km speed increased to 4.08 kbps, which can already be compared with the modem indicators of the 1990s.

< P > Lun Guil, Professor of the University of Vicua and Vice -Cresident of the Beijing Academy of Quantum Information, reported that a prototype of quantum Internet has already been created on the basis of a new protocol. The peculiarity of the developed technique is the use of the same individual photons for both the transmission of information and for the exchange of keys, and this significantly increases efficiency and reduces the risk of signal loss.

~ < P > Scientists predict that in the near future they will be able to double or triple data rate, as well as expand the range of connecting & rsquo; a pitch of up to 150 km or more, which opens prospects for creating a global quantum protected network, which will cover the space. infrastructure.
