Qscale

The QScale project focuses on the development of advanced quantum communication technologies, specifically of quantum repeater architectures, which represent a major and timely challenge for the field of quantum information science and technology. Quantum repeaters are indeed needed in order to overcome losses and errors in the transmission of quantum data. It allows the distribution of entanglement at arbitrary large distances, which is a universal resource for quantum information applications, including quantum cryptography and quantum teleportation. QScale holds the promise for bringing major advances in this field of research. To reach these objectives, the consortium is composed of five academic and one industrial partners. Each team has a leading experience in quantum optics, atomic physics and quantum information processing. The consortium is spanning a variety of physical systems and encoding techniques: cold and ultracold atoms (Laboratoire Kastler Brossel in Paris and Istituto Nazionale di Ottica in Firenze), solid-
