Results in brief
Randomness ad Irreversibility in Physics
The main objective of this project has been to study the various form of randomness, in particular, with respect to the natural capacities of physical and natural systems to "produce" randomness. To this end, we have concentrated on the quantum mechanical features of complementarity and contextuality. The main result obtained is a formal proof for the indeterminism in quantum mechanics, the first attempt to go beyond mere postulation and experimental verification. Our results continue to be cited by the leading authors in quantum computing. The most important application of our strong version of the Kochen-Specker theorem was the blueprint for the first certified by value-indefiniteness quantum random generator (QRG). This QRG is provable better than software-generated randomness.

Project objective
This multidisciplinary exchange programme examines the origins and formal characterization of randomness, indeterminism and irreversibility in physics, as well as their connections.Studies of quantum indeterministic processes and their specification and relation with respect to formal algorithmic and statistical measures of indeterminism and randomness have just started; the area requires profound knowledge of logic, mathematics and computer science, as well as of physics. The rendition of physical indeterminism; e.g., in realizations of physical random number generators, is a very delicate issue, involving, for instance, considerations about the statistical independence of the events which constitute the basis of such devices; as well as the very nature of the randomness resource.Another long-lasting question is how physical irreversibility comes about. The existence of irreversible physical processes and an ""arrow of time"" in statistical physics are often derived by probabilistic arguments, but this remains a delicate issue.In the proposed cooperation, we would like to investigate the connection between physical irreversibility as it relates to indeterminism and randomness. One of our goals is to investigate whether or not irreversibility can be proved from physical indeterminism and randomness.""
