Experimental preparation of states through frustration on a programmable quantum simulator
Alberto Giuseppe Catalano, Ceren DaÄ, Gianpaolo Torre +2
states are a central class of multipartite entangled states with applications in quantum information processing, yet their scalable and deterministic preparation remains challe…
Topological frustration and quantum resources
Alberto Giuseppe Catalano, Gianpaolo Torre, Salvatore Marco Giampaolo +1
Although in general boundary conditions do not affect the bulk properties of a system, some of them are special and defy such expectation. This is the case, for instance, of those…
Numerically efficient unitary evolution for Hamiltonians beyond nearest-neighbors
Alberto Giuseppe Catalano
Matrix product states (MPSs) and matrix product operators (MPOs) are fundamental tools in the study of quantum many-body systems, particularly in the context of tensor network meth…
Resource complexity of Symmetry Protected Topological phases
Alberto Giuseppe Catalano, Sven Benjamin KožiÄ, Gianpaolo Torre +4
We pursue the identification of quantum resources carried by topological order, by evaluating quantum magic, quantified through the rank- Stabilizer Rényi entropy $\mathcal{M}_…
A new rung on the ladder: exploring topological frustration towards two dimensions
Alberto Giuseppe Catalano, Nora ReiniÄ, Gianpaolo Torre +5
Topological frustration arises when boundary conditions impose geometric frustration in a quantum system, creating delocalized defects in the ground states and profoundly altering…
Magic phase transition and non-local complexity in generalized State
A. G. Catalano, J. OdaviÄ, G. Torre +3
We employ the Stabilizer Renyi Entropy (SRE) to characterize a quantum phase transition that has so far eluded any standard description and can thus now be explained in terms of th…
