The many-body dynamics of certain quantum simulators generates a cascade of peculiar entangled states, including spin-squeezed and Schroedinger-cat states. We report on this in our most recent preprint “Multipartite entangled states in dipolar quantum simulators”, now available on arXiv .
Here’s one more way to generate scalable spin squeezing with quantum simulators, when they implement a model featuring spontaneous symmetry breaking. In our new work , with colleagues from Lyon and Villetaneuse, we show that adding a small magnetic field is all you need to do - see also here .
Our study of spin squeezing continues, and we uploaded a new work on arxiv ( link ) where we prove that it captures the first form of correlations appearing in non-equilibrium or adiabatic dynamics.
