Device-independent Quantum Information Processing
The main goal is to understand which quantum information protocols are possible in the device-independent scenario, a framework in which devices are seen as quantum black boxes processing classical information.
This framework is based on Bell non-locality and is especially useful for cryptographic applications, such as secure key distribution or randomness generation, as no assumptions are made on the inner working of these devices except their quantum functioning. Expected outcomes are:
(i) protocols for secure quantum key distribution and randomness generation
(ii) methods to characterize correlations in the black-box scenario
(iii) construction of new Bell inequalities or other tests of quantumness
(iv) methods to self-test quantum states and operations
