Institute for Quantum Information Seminar
Device-independent quantum information
Velario Scarani, Centre for Quantum Technologies and Department of Physics, National University of Singapore
Bell's inequalities can be seen as a family of entanglement witnesses, with a very special property: they detect entanglement without need of prior knowledge on the nature of the system or the measurements. For this reason, they can be used for ``device-independent" assessment.
In this talk, I shall review the main results in device-independent quantum cryptography , self-testing of a source of entanglement  and others; then I shall focus on randomness generation  and in particular on the case where the initial seed has imperfect randomness ("reduced measurement independence" or "reduced free will") .
