  Quantum key distribution (QKD) is a cornerstone of the secure quantum
encryption. Building on the quantum irreversibility, we develop a technique
reborning the existing QKDs into protocols that are unrestricted in distance
and have unprecedented high rates enhanced up to the standard protocols
communication speeds. The core of our method is the continuous end-to-end
physical control of information leaks in the quantum channel. Contrary to the
existing long-distance QKD offerings, our technique does not require any trust
nodes.
