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…
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…
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…
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…
Exploring the Effect of Basis Rotation on NQS Performance
Sven Benjamin KožiÄ, Vinko ZlatiÄ, 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…
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…
