RESOURCES FOR QUANTUM INFORMATION

Objective

The project "Resources for Quantum Information" (RESQ) is an interdisciplinary project with partners from physics, computer science, and mathematics and statistics backgrounds. Specific objectives of the project are to develop new protocols and algorithms for processing information at the quantum level, particularly in networks and distributed systems and in the presence of noise, to develop specific applications for small scale quantum systems, to devise tests of quantum devices, to further characterize quantum entanglement, and to further characterize the resources required to carry out quantum information processing.

OBJECTIVES
The general objective of the project is - to understand how quantum information can be manipulated in small scale systems, - to improve our understanding of the nature of quantum information, both at a fundamental level and from the pragmatic point of view of testing quantum systems, - and to understand how information can be processed in distributed quantum systems, both from the point of view of algorithms and from the point of view of security and cryptography.

DESCRIPTION OF WORK
The work iN divided in three work packages, corresponding to the three objectives stated above 1. In work package 1, small-scale systems will be dealt with. The project will characterize entanglement (for instance using techniques borrowed from communication complexity, or using numerical methods), devise quantum algorithms specifically adapted to small scale systems, devise novel schemes for quantum information processing based on specific physical systems, and will characterize the advantages / disadvantages of quantum information using systems of dimension greater than two;
2. In work package 2, "quantumness" will be studied from the theoretical and pragmatic point of view. The project will design tests of quantumness of devices based on Bell inequalities, and it will design tests of correctness of quantum devices. Furthermore the project will design improved techniques for estimating quantum states and for estimating quantum dynamics; it will characterize resources required for carrying out quantum dynamics, quantum communication and quantum computation; and it will develop new concepts in classical information theory based on analogies with quantum information;
3. In work package 3, the subject is "networks": information processing in distributed quantum systems. The project will devise methods to carry out distributed quantum computing; it will generalize the Byzantine agreement problem and adapt it to realistic experimental conditions; it will devise methods for quantum coin flipping, and it will characterize the security of quantum cryptography, and in particular its relation to Bell inequalities. The consortium for this project combines the expertise from physicists, computer scientists and mathematicians in a collaborative research effort to achieve the above objectives. In this way, the project will also contribute to "closing the persistent cultural gap between computer scientists and physicists/engineers" as observed by the European Commission.
