Scientists of Moscow State University (MSU) have presented a communication system working on quantum information protection technology. The basic information is transmitted using the usual encrypted protocols while the main part of the system - the quantum key distribution server- is responsible for the encryption keys.

Encryption systems that are not vulnerable to direct hacking have been around for a long time, even if you go through all the possible keys. The main method for gaining access to information is the interception of keys at the time when the parties exchange them. A quantum bond solves this problem.

The encoding protocol is based on quantum states of photons so no one can overhear conversations unnoticed, since these states always change.

The inventors tested a system in which information was transmitted over an optical fiber. The testers were connected by a 50 km long cable and a line of 25 km was stretched from each participant to the quantum key distribution server. The server occupied eight standard server racks, but in the future it is planned to be reduced by half.

The downside of the technology so far is it's short range (up to 100 km) because of the complexity of maintaining stable quantum states. The speed of the connection is also not very large compared to conventional communication systems.

In 2016, the Russian Quantum Center already tested a 30-kilometer quantum communication line. Chinese scientists managed to launch a satellite of quantum communication, in which they managed to make a call between the Chinese and Austrian academies of science.

Some of the largest corporations such as Google, IBM, and Microsoft are leading the race in quantum computers, introducing the world to more and more powerful developments.
