"From Bell's theorem to the device-independent quantum information paradigm”
Antonio Acin, ICREA & ICFO, Barcelona, Spain
ABSTRACT
Bell’s theorem proved the existence of quantum correlations with no classical analogue. After reviewing this fundamental result, we show how Bell non-local correlations are the crucial ingredient for device-independent quantum information applications. In this paradigm, devices are seen as uncharacterised quantum black boxes processing classical information and protocols are built without requiring any device modelling. This device-independent property guarantees that the protocol performance is self-certified and, in particular, provides the strongest form of quantum security.
SHORT BIO
Antonio Acín is an ICREA Research Professor at ICFO-The Institute of Photonic Sciences. He has a degree in Physics from the Universitat de Barcelona (UB) and in Telecommunication Engineering from the Universitat Politècnica de Catalunya. He got his PhD in Theoretical Physics in 2001 from the UB. After a post-doctoral stay in Geneva, he joined ICFO in 2003. At ICFO, Acín leads the Quantum Information Theory group. The group activities focus on quantum information theory and quantum communication, with an emphasis on quantum cryptography, but also cover other fields such as quantum optics, many-body physics, quantum thermodynamics, of the foundations of quantum physics. Acín's research has been awarded with 4 grants from the European Research Council: 1 Starting, 1 Proof of Concept, 1 Consolidator and 1 Advanced Grant, the latter starting in 2020. He also received an AXA Chair in Quantum Information Science in 2016.
