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…
Experimental preparation of states through frustration on a programmable quantum simulator
Alberto Giuseppe Catalano, Ceren Dağ, 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…
A new rung on the ladder: exploring topological frustration towards two dimensions
Alberto Giuseppe Catalano, Nora Reinić, Gianpaolo Torre +5
Topological frustration arises when boundary conditions impose geometric frustration in a quantum system, creating delocalized defects in the ground states and profoundly altering…
Computing Quantum Resources using Tensor Cross Interpolation
Sven Benjamin Kožić, Gianpaolo Torre
Quantum information quantifiers are indispensable tools for analyzing strongly correlated systems. Consequently, developing efficient and robust numerical methods for their computa…
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…
Odd thermodynamic limit for the Loschmidt echo
Gianpaolo Torre, Vanja Marić, Domagoj Kuić +2
Is it possible to readily distinguish a system made by an Avogadro's number of identical elements and one with a single additional one? Usually, the answer to this question is nega…
Topological Frustration can modify the nature of a Quantum Phase Transition
Vanja Marić, Gianpaolo Torre, Fabio Franchini +1
Ginzburg-Landau theory of continuous phase transitions implicitly assumes that microscopic changes are negligible in determining the thermodynamic properties of the system. In this…
Effects of defects in the XY chain with frustrated boundary conditions
Gianpaolo Torre, Vanja Marić, Fabio Franchini +1
It has been recently proven that new types of bulk, local order can ensue due to frustrated boundary condition, that is, periodic boundary conditions with an odd number of lattice…
Non-Markovianity-assisted optimal continuous variable quantum teleportation
Gianpaolo Torre, Fabrizio Illuminati
We study the continuous-variable (CV) quantum teleportation protocol in the case that one of the two modes of the shared entangled resource is sent to the receiver through a Gaussi…
Exact non-Markovian dynamics of Gaussian quantum channels: Finite-time and asymptotic regimes
Gianpaolo Torre, Fabrizio Illuminati
We investigate the Markovian and non-Markovian dynamics of Gaussian quantum channels, exploiting a recently introduced necessary and sufficient criterion and the ensuing measure of…
Quantum coherence of Gaussian states
Daniela Buono, Gaetano Nocerino, Giuseppe Petrillo +3
We introduce a geometric quantification of quantum coherence in single-mode Gaussian states and we investigate the behavior of distance measures as functions of different physical…
Asymptotic non-Markovianity
Giuseppe Petrillo, Gianpaolo Torre, Fabrizio Illuminati
We investigate the asymptotic dynamics of exact quantum Brownian motion. We find that non-Markovianity can persist in the long-time limit, and that in general the asymptotic behavi…
Non-Markovianity of Gaussian Channels
Gianpaolo Torre, Wojciech Roga, Fabrizio Illuminati
We introduce a necessary and sufficient criterion for the non-Markovianity of Gaussian quantum dynamical maps based on the violation of divisibility. The criterion is derived by de…
