In spite of the explosion of interest for the role played by the notion of Information in the foundations of quantum theory and spacetime physics, we are far from having a shared and clear understanding of what we mean by Information. Different research groups use this notion in the context of different perspectives. Dialogue and a common theoretical framework for Quantum Information and Quantum Gravity can clarify the role of Information in quantum gravitational physics and foster a major breakthrough in our understanding of what we call space and time.
The two research communities of Quantum Information and Quantum Gravity face parallel questions regarding the conceptual foundation of our understanding of the world. Quantum theory and general relativity have modified our notions of Locality and Objectivity on the one hand, and Space and Time on the other. As much as these modifications deepen our understanding of reality, they also reveal our ignorance: in light of what we have learnt, what can we say about what is an objective fact? What can we say about the spatial and temporal localization of facts? Does `happening’ necessarily presuppose ‘somewhere, sometime, with respect to somebody’? What are we, the observers, and what is the information we have about reality in a world where everything, including us and the space and time we inhabit, are quantum entities? What kind of physical systems are we, human beings, in such a world no longer captured by the naive scientific materialism of old mechanical philosophy? What is the appropriate conceptual structure for capturing our current knowledge?
The QISS project brings together leading scientists from both research communities interested in facing these basic questions, including theorists, experimentalists and a group of leading philosophers of science. Consortium members research questions at the foundations of basic science from a multiplicity of points of view, from pure philosophy to the laboratory bench. QISS provides a forum for fertile dialogue between the broader communities of Quantum Information and Quantum Gravity, catalysing cross–disciplinary collaborations.
