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…

Computing Quantum Resources using Tensor Cross Interpolation
Sven Benjamin KožiÄ, Gianpaolo Torre
Quantum information quantifiers are indispensable tools for analyzing strongly correlated systems. Consequently, developing efficient and robust numerical methods for their computa…
