Quantum many-body physics at equilibrium or away from it generates entangled states, which are by far the most challenging objects known in nature to study using classical computers. Yet not all entangled states are equal: some states have a very transparent form of entanglement, because the latter can be detected by measuring simple observables, which appear in so-called entanglement criteria. In turn, entanglement manifesting itself in accessible observables may often appear as an immediate resource: e.g., it can fundamentally alter the way in which quantum states transform under unitary transformations forming in this way the basis of entanglement-assisted metrology. In this talk I will provide some relevant examples of how these â€œresourcefulâ€ entangled quantum states can be studied theoretically; and of how they can potentially be generated under realistic conditions by state-of-the-art quantum simulators.
Prof. Tommaso Roscilde is a Professor at the Ecole Normale SupÃ©rieure de Lyon, in France. He did his PhD from the University of Padova in Italy and then he was Postdoctoral Fellow at the University of Southern California and the Max Planck Institute of Quantum Optics. Then he joined the Ecole Normale SupÃ©rieure de Lyon. His research interests are in the field of theory of quantum simulation, i.e., the controlled realization of complex quantum systems in the experiments of atomic physics and condensed matter.
