Entanglement spectrum and magic in higher-dimensional free fermionic systems
Beatrice Magni, Daniele Iannotti, Riccardo Travaglino
We study fermionic non-local magic in higher-dimensional free-fermion systems through the lens of the entanglement spectrum. For translationally invariant Gaussian states in strip…
Colored Weingarten Calculus for Block-Unitary Ensemble
Daniele Iannotti, Elisa Vallini
Haar randomness is the standard null model for quantum typicality, scrambling, and random-matrix formulations of thermalization. In many physical settings, however, randomness is n…
A journey through Flatland: What does the antiflatness of a spectrum teach us?
Barbara Jasser, Daniele Iannotti, Alioscia Hamma
We explore the concept of antiflatness to characterize the structural fluctuations within the entanglement spectrum of a quantum state (i.e., the spectrum of its reduced density op…
Non-stabilizerness and U(1) symmetry in chaotic many-body quantum systems
Daniele Iannotti, Angelo Russotto, Barbara Jasser +2
We present exact, closed-form results for the non-stabilizerness of random pure states subject to a U(1) symmetry constraint. Using stabilizer entropy as our non-stabilizerness mon…
Non-Local Magic Resources for Fermionic Gaussian States
Daniele Iannotti, Beatrice Magni, Riccardo Cioli +2
Entanglement and magic are fundamental resources that capture the complexity of quantum many-body systems. Non-local magic isolates the irreducible nonstabilizerness intrinsically…
Van Hove singularities in stabilizer entropy densities
Daniele Iannotti, Lorenzo Campos Venuti, Alioscia Hamma
The probability distribution of a measure of non-stabilizerness, also known as magic, is investigated for Haar-random pure quantum states. Focusing on the stabilizer Rényi entropie…
Non-stabilizerness and violations of CHSH inequalities
Stefano Cusumano, Lorenzo Campos Venuti, Simone Cepollaro +7
We study quantitatively the interplay between entanglement and non-stabilizer resources in violating the CHSH inequalities. We show that, while non-stabilizer resources are necessa…
Entanglement and Stabilizer entropies of random bipartite pure quantum states
Daniele Iannotti, Gianluca Esposito, Lorenzo Campos Venuti +1
The interplay between non-stabilizerness and entanglement in random states is a very rich arena of study for the understanding of quantum advantage and complexity. In this work, we…
Geometric methods in quantum information and entanglement variational principle
Daniele Iannotti, Alioscia Hamma
Geometrical methods in quantum information are very promising for both providing technical tools and intuition into difficult control or optimization problems. Moreover, they are o…
Twisted Index on Hyperbolic Four-Manifolds
Daniele Iannotti, Antonio Pittelli
We introduce the topologically twisted index for four-dimensional gauge theories quantized on . We compute the index by applying supersymmetr…
