Experimental demonstration of non-local magic in a superconducting quantum processor
Halima Giovanna Ahmad, Gianluca Esposito, Viviana Stasino +9
Non-local magic is the non-stabilizerness that no local unitary operation can erase. It captures the joint action of entanglement and magic underlying quantum advantage, and it has…
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…
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…
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…
Friedel oscillations of one-dimensional correlated fermions from perturbation theory and density functional theory
Jovan Odavić, Nicole Helbig, Volker Meden
We study the asymptotic decay of the Friedel density oscillations induced by an open boundary in a one-dimensional chain of lattice fermions with a short-range two-particle interac…
