Distribution of quantum keys over commercial networks

Abstract

[EN]Modern cryptography – as it was conceived – is under a threat by the development of quantum mechanics applications. The abilities of quantum computers for solving complex mathematical problems, as a strong computational novelty, is the root of that risk. The main challenge is to find commercial exploits of quantum properties and developments, following these directions for both, theoretic and test tube environments. This work proposes a pilot experiment that implements a quantum communication system on a commercial fiber optic network, covering an area of almost 100,000 km2.
