"Quantum information with Black Boxes"

Who: Prof. Antonio Acin, ICFO

Place: Donostia International Physics Center

Date: Monday, 27 November 2017, 12:00

Device-independent quantum information processing represents a new framework for quantum information applications in which devices are just seen as quantum black boxes processing classical information. This level of abstraction makes them especially relevant for cryptographic applications, as (i) protocols can be certified by the user without requiring any trust on the provider and (ii) existing quantum hacking attacks become impossible. Device-independent protocols are possible in quantum physics because of the existence of correlations without classical counterpart, as predicted by Bell?s theorem. The talk provides an overview on the device-independent scenario, with a focus on the motivations, existing results and applications.
