Quantum communications are a form of information transmission that depends on encryption based on quantum physics to codify data in one light particles called photons.
QKD is one of the ways that depends on the exchange of secret keys between two parties that are used to decompose information, which makes it difficult to listen to listen and theoretically.
“However, it is widely known that real QKD devices can be vulnerable to different types of side canal attacks that depend on defects in experimental implementation,” said quantum researcher Alexander Miller.
After analyzing the data obtained during the connection between a ground station and a mechanism, Miller found time delays between the laser on the quantitative transmission device on the plane, showing that “the distribution of quantum keys from Micius was unsafe.”
