Project: Experimentally-oriented Device Independent CrypTography

Acronym	eDICT
Project Topic	Current state-of-the art quantum-assisted cryptography provides safety beyond what can be achieved with current classical technologies. Yet still, its safety is at question when we consider possibilities of quantum hacking or malicious producers of necessary quantum resources. This project aims at overcoming these main limitations by radically shifting current paradigms—by using device independent cryptographic (DIC) architecture. This is on one hand more demanding on experimental resources and theoretical understanding but on the other hand provides qualitative improvement in safety. DIC devices would then be not only safe against exploiting deviations of a real life from theoretical model but they would also have possibility of verification whether using such a device is secure.The success of the project stands both on firm theoretical foundations of various backgrounds and high-quality experimental realisation. This can be achieved only with the composition of partners with high interdisciplinary reach. Our consortium contains excellent groups covering all necessary parts within the project with their expertise both on theoretical as well as experimental sides. With synergic effort we will devise new more efficient Bell inequalities with improved critical detection efficiency bounds, derive new tools for device independent and iid analysis, and design new DIC key distribution protocols. On experimental side our aim is to provide a test-bed for researched Bell inequalities. Namely we will perform practical tests of the possible state production.
