The interplay between Quantum Optics, Quantum Information Theory and Quantum Statistical Physics has been leading to a new trend in contemporary physics. On one hand, new views into statistical physics are provided, with spin-offs that could lead to decisive progress in the applications, including condensed matter. On the other hand, strongly correlated quantum statistical systems, considered as platforms for quantum devices, naturally provide correlations that quantum technologies aims at exploiting as a resource. In this talk I will discuss my latest contributions to the field, in both the above directions. Specifically : i) I will discuss how the notion of Local operation and classical operations (LOCC) can be exploited to describe quantum phases of matter, beyond the Landau symmetry breaking paradigm. I will point out how such an approach can lead to a local characterization of the topological matter/spin liquids, opening the way to experimental tests. ii) I will show how neutral currents flowing through ring-shaped optical lattices, effectively provides a cold atoms-analog of the flux qubits based on SQUID device. The lattice along the rings makes the system strictly one dimensional and provides the infrastructure for a feasible qubit-qubit interaction.
