ABSTRACT
In the domain of research associated to quantum information, quantum cryptography has solved a major issue of current protocols which is the key distribution between two interlocutors, by guaranteeing that no other person can have knowledge of it. The quantum key distribution thus allows for data securitization for a much longer period of time than that obtained at this time. Initially presented as a mere curiosity, this technique has now proved its potential, although its development requires new tools such as sources or single-photon detectors.

INTRODUCTION
Quantum cryptography requires the development of new tools, such as sources and single-photon detectors. In the case of sources, it is essential to be able to work with a single quantum system, such as a semiconductor quantum box, in a photonic crystal structure. In the case of detectors, it is necessary to master the nanofabrication of components in order to increase quantum efficiency and reduce noise.
