Japan has begun work on a global quantum key distribution service. As part of the project, by 2024, it is planned to build a network that includes more than 100 quantum cryptographic devices and 10,000 users around the world, writes The Register. Four technologies will also be developed:

- the technology of quantum communication (Quantum Communications Link Technology), realizing high-speed, backbone, highly available connection in quantum cryptographic communication networks;
- the technology of trusted nodes (Trusted Node Technology), providing reliability and protection against hacking of cryptographic key management systems, as well as increasing confidentiality, integrity and availability of quantum cryptographic communications;
- the technology of a quantum relay (Quantum Relay Technology), extending distances and protecting the relay of cryptographic keys on the ground;
- the technology for the construction and operation of global networks, which controls and controls global and large-scale quantum cryptographic communication networks.

Quantum encryption sees keys encrypted in the quantum state of a particle, often an entangled photon. Since in quantum mechanics, measuring a quantum state causes it to change, you can tell if someone has tried to see the quantum key. This will allow you to identify compromised keys and take appropriate action.

While the basics of quantum encryption are well understood, and there have even been demonstrations of quantum key distribution between Earth and space, key sharing and distribution are still rare.

Toshiba and NEC, as well as several Japanese universities, are working on a global quantum key distribution service. The Japanese government allocated $ 13.3 million for the implementation of the project in the first year

We will remind you, on July 23 of this year at the University of Chicago was presented the project of the quantum Internet. According to the plan, in about a year, scientists should create a quantum communication channel between the laboratory of the University of Chicago and the Fermi National Laboratory in Batavia (Chicago, USA).

Quantum key distribution is a key transfer method that uses quantum phenomena to provide secure communications. This method allows two parties connected through an open communication channel to create a shared random key known only to them and use it to encrypt and decrypt messages.
