eDICT (QuantERA)

Experimentally-oriented Device Independent CrypTography
Principal Investigator:	Assoc. Prof. RNDr. Jan Bouda, Ph.D.
Project Period:	1/2020- 12/2022
	Details

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 testbed for researched Bell inequalities. Namely we will perform practical tests of the possible state production.

RAQUEL

Randomness and Quantum Entanglement (323970)
Principal Investigator:	Assoc. Prof. RNDr. Jan Bouda, Ph.D.
Project Period:	10/2013 - 9/2016
	Details

Randomness has established itself as a vital building block of information processing and represents an integral ingredient for practically any aspect in the field of information processing and technology. The principal objective of this project will be to establish and evaluate the role played by randomness in quantum information processing. We propose to address the main difficulties that arise through the use of randomness, in particular,

the use of randomness as a theoretical tool to prove existence and properties
of information processing applications;
the design of novel quantum information processing
applications that exploit randomness;
the design and analysis of applications
that work with real-world (that is, non-uniform) randomness;
the construction of design
techniques that produce high-quality randomness, both from a computational and
adversarial perspective; and, finally,
the use of randomness to analyze and improve
the physical processes necessary for the design quantum communication and computation
devices.

The consortium aims to unite the forces of EU expertise in computer science, physics and mathematics to undertake a comprehensive study of randomness and quantum information within their research portfolio. Many of the targeted tasks combine the knowledge of partners. Hence, strong research interactions will be necessary to successfully achieve the objectives of the project.
