Abstract

The spectacular development of quantum over the past few years has sparked renewed interest in quantum information. In addition to quantum computation, recent advances permit to envision revolutionary technological developments in quantum simulation, quantum metrology, and quantum communications. Still, many fundamental questions remain unanswered regarding the very foundations of quantum information, first and foremost quantum correlations and entanglement. We are only just beginning to understand the close relationship between quantum information and correlated quantum matter, for instance on emerging phenomena such as phase transitions. Another equally fundamental question is to understand how information propagates in correlated quantum systems, with applications of prime importance not only for quantum communications, but also for the foundations of statistical physics and the ergodicity of isolated systems. The study of these questions is particularly suited to close collaboration between theory and experiments realized out on new quantum control devices.
This project aims to explore two aspects of these questions:
(i) The role of entanglement in quantum phase transitions;
(ii) Propagation of information in correlated quantum systems.
