Accelerating the development of “unbreakable” quantum cryptographic communication, with domestic companies also rushing to commercialize it. Current cryptographic codes used on the Internet and elsewhere are at risk of being broken with the advent of quantum computers.

Quantum cryptographic communication transmits encryption key information on light particles (photons) and shares it with the other party. Eavesdropping can be detected by taking advantage of the property of quantum mechanics that the state changes when observed, and theoretically it is impossible to decipher it.
