Special Issue Information

Dear Colleagues,

Quantum technologies have evolved from successful laboratory experiments to real-world implementation, with quantum key distribution probably being the most mature quantum-based technology available nowadays. Quantum random number generators, entangled or heralded photon-pair sources and single-photon detectors are other examples of quantum technologies available in the market. Considering the current state of the art of this rapidly expanding research field, it is easy to foresee a completely new set of functionalities and dedicated services to the information and communication society, enabled by such quantum technologies in a very disruptive way.

The aim of this Special Issue is to highlight the recent progress and trends in quantum technologies, with special focus on its applications to quantum key distribution, quantum commitment and quantum oblivious transfer protocols. The accepted papers will demonstrate a diversity of new developments in these areas. For this Special Issue, high-quality articles reporting original research results and survey articles of exceptional merit are welcome for submission, and it will let the readers of this journal to be aware of the most recent outcomes and trends of this fundamental research area.

Quantum key distribution protocols allow two honest distant parties to establish a common truly random secret key in the presence of powerful adversaries, provided that the two users share a short secret key beforehand. This pre-shared secret key is used mainly for authentication purposes in the post-processing of classical data that have been obtained during the quantum communication stage, and it prevents a man-in-the-middle attack. The necessity of a pre-shared key is usually considered to be the main drawback of quantum key distribution protocols, and it becomes even stronger for large networks involving more than two users. Here, we discuss the conditions under which physical unclonable functions can be integrated in currently available quantum key distribution systems in order to facilitate the generation and the distribution of the necessary pre-shared key with the smallest possible cost in the security of the systems. Moreover, the integration of physical unclonable functions in quantum key distribution networks allows for real-time authentication of the devices that are connected to the network. Full article
