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…
Rise and fall of nonstabilizerness via random measurements
Annarita Scocco, Wai-Keong Mok, Leandro Aolita +2
We investigate the dynamics of nonstabilizerness - also known as `magic' - in monitored quantum circuits composed of random Clifford unitaries and local projective measurements. Fo…
Integrability and Chaos via fractal analysis of Spectral Form Factors: Gaussian approximations and exact results
Lorenzo Campos Venuti, Jovan Odavić, Alioscia Hamma
It is well known that the spectral form factor (SFF) of a possibly degenerate many-body Hamiltonian can be identified with a planar random walk taking steps of unequal length. In t…
Programmable non-Hermitian photonic quantum walks via dichroic metasurfaces
Paola Savarese, Sarvesh Bansal, Maria Gorizia Ammendola +6
The evolution of a closed quantum system is described by a unitary operator generated by a Hermitian Hamiltonian. However, when certain degrees of freedom are coupled to an environ…
Interplay of entanglement structures and stabilizer entropy in spin models
Michele Viscardi, Marcello Dalmonte, Alioscia Hamma +1
Understanding the interplay between nonstabilizerness and entanglement is crucial for uncovering the fundamental origins of quantum complexity. Recent studies have proposed entangl…

Giulia Salatino, Maximilian Matzler, Annarita Scocco +2
Diabatic quantum annealing aims to mitigate the challenges posed by small energy gaps and decoherence in quantum optimization by exploiting nonadiabatic transitions. In this paper,…
Stabilizer Entropy and entanglement complexity in the Sachdev-Ye-Kitaev model
Barbara Jasser, Jovan Odavić, Alioscia Hamma
The Sachdev-Ye-Kitaev (SYK) model is of paramount importance for the understanding of both strange metals and a microscopic theory of two-dimensional gravity. We study the interpla…

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…
Harvesting stabilizer entropy and non-locality from a quantum field
S. Cepollaro, S. Cusumano, A. Hamma +2
The harvesting of quantum resources from the vacuum state of a quantum field is a central topic in relativistic quantum information. While several proposals for the harvesting of e…
Stabilizer entropy in non-integrable quantum evolutions
Jovan Odavić, Michele Viscardi, Alioscia Hamma
Entanglement and stabilizer entropy are both involved in the onset of complex behavior in quantum many-body systems. Their interplay is at the root of complexity of simulability, s…
Quantum adiabatic optimization with Rydberg arrays: localization phenomena and encoding strategies
Lisa Bombieri, Zhongda Zeng, Roberto Tricarico +5
Quantum adiabatic optimization seeks to solve combinatorial problems using quantum dynamics, requiring the Hamiltonian of the system to align with the problem of interest. However,…
Invested and Potential Magic Resources in Measurement-Based Quantum Computation
Gongchu Li, Lei Chen, Si-Qi Zhang +8
Magic states and magic gates are crucial for achieving universal quantum computation, but important questions about how magic resources should be implemented to attain maximal quan…
