Specialists from the Center for Quantum Technologies of Moscow State University and SFB Lab have presented a new quantum key distribution protocol that is resistant to the most dangerous attacks, the university's press service reported.
The developed protocol is of the point-to-point type and protects against attacks that impose a quantum state. Previously, they were considered one of the most serious threats. In the course of the work, the stability of the protocol was proven under ideal conditions. Scientists also investigated the influence of possible imperfections in the preparation and measurement of quantum states on its protection.
The protocol developed by scientists can be used in space quantum key distribution systems, where the constant rotation of satellites can create difficulties with calibration. The new solution does not require additional calibration.
