Goals of the eDICT project

Current state-of-the-art quantum-assisted cryptography provides safety beyond what can be achieved with current classical technologies. Yet still, its safety is in 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 a qualitative improvement in safety. DIC devices would then be not only safe against exploiting deviations of a real-life from the theoretical model but they would also have the 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 realization. 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 the experimental side, our aim is to provide a testbed for researched Bell inequalities. Namely, we will perform practical tests of the possible state production.

Partners

Masaryk university

Faculty of Informatics - Quantum Information group

Principal investigator: Jan Bouda

Co-investigators:

  • Mário Ziman
  • Daniel Reitzner
  • Michal Sedlák
  • Libor Caha

Group description:

The research team is multidisciplinary and combines expertise from informatics and physics. All the members have strong quantum information processing background. Several of the members of the research team have been cooperating since 2000 and have been part of the research team for several successful national and EU projects. The research team has an established and strong international collaboration with leading groups in the field. This is clearly manifested by joint papers and visits. Strong international collaboration is also established through the Central-European Quantum Information Processing workshops (around 50 participants from more than 10 countries worldwide every year), organized by the research team. Over the last five years, members of the team have published more than 35 papers (WOK) in impacted scientific journals or top conferences (CRYPTO) and gave 11 invited talks all over the world.


 

Österreichische Akademie der Wissenschaften

Institute for Quantum Optics and Quantum Information Vienna

[This partner does not receive funding from eDICT project but is our lead partner with a common goal in achieving eDICT objectives]

Principal investigator: Rupert Ursin

Co-investigators:

  • Miguel Navascues
  • Martin Bohmann

Group description:

The team of Rupert Ursin is internationally well known for the implementation of quantum optics experiments mainly in the field of quantum communication over long-distances. In addition to that, he published a series of papers describing experiments and the data analysis tools used with regard to a so-called loophole-free Bell experiment. This paper is highly cited (according to ISI Web of Knowledge) and is special in the sense that the statistics is significant meaning the most photon pairs produced so far in this special field. This makes him the logical candidate for the experimentalist within the consortium.


 

Uniwersytet Gdański

International Centre for Theory of Quantum TechnologiesQuantum Information group

Principal investigator: Marcin Pawłowski

Co-investigators:

  • Piotr Mironowicz
  • Nikolai Miklin
  • Chithra Raj

Group description:

Quantum Information group at the University of Gdańsk is one of the leading quantum theory groups in the world. It was the origin of many groundbreaking works on Bell inequalities, quantum entanglement, and foundations of physics. Thanks to numerous, well-established collaborations, the ideas developed in Gdańsk have seen their experimental realizations in laboratories all around the world. Recently it acquired a prestigious IRAP grant enabling it to open International Centre for Theory of Quantum Technologies (ICTQT), which is currently kickstarting its operations.

  • Erika Bene

Group description:

The MTA Atomki is part of the Hungarian Academy of Sciences, whose activity is highly interdisciplinary and concerns both theoretical and experimental fundamental research focusing on atomic, nuclear, particle and astrophysics. It carries out cutting edge research with large-scale international collaborations (e.g. CERN-CMS, LIGO-EGRG, LUNA, etc.), making balanced use of the local infrastructure and that of the leading international research centers. Atomki hosts several research projects (1 ERC grant, 15 other EU funded projects, 2 CERN projects, 2 IAEA projects) and is also famous for popularization of science. Several outreach activites are hosted including the international Science on Stage festival taking place at Atomki in June 2017.
