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…
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 and entanglement complexity in the Sachdev-Ye-Kitaev model
Barbara Jasser, Jovan OdaviÄ, 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…
Magic phase transition and non-local complexity in generalized State
A. G. Catalano, J. OdaviÄ, 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-distance genuine multipartite Entanglement between Magnetic Defects in Spin Chains
Mirko Consiglio, Jovan OdaviÄ, 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…
