Schmidt-Gauge Non-Local Magic: Representation, Optimality, and Mathematical Properties
Fabio Franchini, Salvatore Marco Giampaolo
While the full non-stabilizerness (magic) of a quantum state contains local, basis-dependent contributions, a non-local formulation based on a minimization over local unitaries iso…
Non-Local Magic from the Entanglement Spectrum
Gianpaolo Torre, Fabio Franchini, Salvatore Marco Giampaolo
Non-local magic has recently emerged as a fundamental resource for characterizing genuinely non-local non-stabilizer correlations. However, its direct calculation is an intractable…
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…
Exploring the Effect of Basis Rotation on NQS Performance
Sven Benjamin Kožić, Vinko Zlatić, Fabio Franchini +1
Neural Quantum States (NQS) are powerful variational representations of quantum many-body wavefunctions, yet their performance depends sensitively on the chosen basis. Using an exa…
Resource complexity of Symmetry Protected Topological phases
Alberto Giuseppe Catalano, Sven Benjamin Kožić, 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}_2…
Experimental preparation of states through frustration on a programmable quantum simulator
Alberto Giuseppe Catalano, Ceren Dağ, 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…
A new rung on the ladder: exploring topological frustration towards two dimensions
Alberto Giuseppe Catalano, Nora Reinić, 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…
A Breakdown Case Study of the Lindblad Approach via Entanglement and Purity
Raoul Serao, Aniello Quaranta, Antonio Capolupo +2
The Lindblad master equation is widely used to describe the reduced dynamics of open quantum systems under Markovian assumptions. Here, we investigate its ability to reproduce the…
Quantum Coherence of Topologically Frustrated Spin Chains
S. B. Kožić, G. Torre, K. Delić +2
The study of entanglement and magic properties in topologically frustrated systems suggests that, in the thermodynamic limit, these quantities decompose into two distinct contribut…
Long-distance genuine multipartite Entanglement between Magnetic Defects in Spin Chains
Mirko Consiglio, Jovan Odavić, Riccarda Bonsignori +5
We investigate the emergence and properties of long-distance genuine multipartite entanglement, induced via three localized magnetic defects, in a one-dimensional transverse-field…
Magic phase transition and non-local complexity in generalized State
A. G. Catalano, J. Odavić, 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…
Towards a phase diagram of the topologically frustrated XY chain
Daniel Sacco Shaikh, Alberto Giuseppe Catalano, Fabio Cavaliere +3
Landau theory's implicit assumption that microscopic details cannot affect the system's phases has been challenged only recently in systems such as antiferromagnetic quantum spin c…
Long-range entanglement and topological excitations
Gianpaolo Torre, Jovan Odavić, Pierre Fromholz +2
Topological order comes in different forms, and its classification and detection is an important field of modern research. In this work, we show that the Disconnected Entanglement…
Random unitaries, Robustness, and Complexity of Entanglement
J. Odavić, G. Torre, N. Mijić +3
It is widely accepted that the dynamic of entanglement in presence of a generic circuit can be predicted by the knowledge of the statistical properties of the entanglement spectrum…
Complexity of frustration: a new source of non-local non-stabilizerness
J. Odavić, T. Haug, G. Torre +3
We advance the characterization of complexity in quantum many-body systems by examining -states embedded in a spin chain. Such states show an amount of non-stabilizerness or "ma…
