"With QITBOX we aim to develop a novel device-independent framework for quantum information processing. In this framework, devices are seen as black boxes that only receive inputs and produce outputs. Our main objective is to understand what can and cannot be done for information processing using only the observed correlations among the devices. We will structure our effort along three main research lines: (i) Characterization of quantum correlations: the general objective will be to characterize those correlations that are possible among quantum devices; (ii) Protocols based on correlations: the general objective will be to understand how quantum correlations can be exploited in order to construct relevant information protocols and (iii) Applications to physical setups: here the previous results to concrete physical setups will be applied, such as the quantum-optical realizations of the protocols or the study of the non-local properties of many-body systems. The expected results of QITBOX are: (i) Novel methods for the characterization of quantum correlations, (ii) Improved or novel device-independent protocols, (iii) Proposals for feasible experimental implementations of these protocols and (iv) Novel methods for the study of many-body systems based on correlations. QITBOX is a highly-interdisciplinary project with implications in Physics, Mathematics, Computer Science and Engineering. The execution of the planned research work will provide a unifying framework for a Quantum Information Theory with black BOXes (hence the acronym). Such a framework will bring quantum information processing to an unprecedented level of abstraction, in which information protocols and primitives are defined without any reference to the internal physical working of the devices. This, in turn, will lead to much more robust practical implementations of quantum information protocols, closing the mismatch between theoretical requirements and experimental realisations."
