Device-Independent Quantum Information Processing represents a new paradigm for
quantum information processing: the goal is to design protocols to solve relevant information
tasks without relying on any assumption on the devices used in the protocol. For instance,
protocols for device-independent key distribution aim at establishing a secret key between
two honest users whose security is independent of the devices used in the distribution.
Contrary to standard quantum information protocols, which are based on entanglement, the
main resource for device-independent quantum information processing is quantum nonlocality.
Apart from the conceptual interest, device-independent protocols offer important
advantages from an implementation point of view: being device-independent, the realizations
of these protocols, though technologically challenging, are more robust against device
imperfections. Current and near-future technology offer promising perspectives for the
implementation of device-independent protocols.
This project explores all these fascinating possibilities. Its main objectives are (i) obtaining a
better characterization of non-local quantum correlations from an information perspective, (ii)
improve existing and derive new application of this resource for device-independent quantum
information processing and (iii) design feasible implementations of device-independent
protocols. We plan to tackle these questions with an inter-disciplinary approach combining
concepts and tools from Theoretical and Experimental Physics, Computer Science and
