Project Annotation: Recent advances in Quantum Gravity -the effort to understand the quantum properties of space and time- point to a central role played by the notion of Information: quantum theory gives the observer a role, replacing the objective spacetime substratum with an observer–dependent informational structure. Recent advances in Quantum Information have shown that information theoretical tools naturally describe evolution of quantum geometry, have explored non-trivial causal structures, and the role these can play in Quantum Computing. The convergence between these two vibrant research domains raises foundational issues that question the hearth of our understanding of the world: Is there a deep connection between Information and the nature of Space and Time? Are space and time losing their role as grounds for an objective physical reality?
