Harnessing a 256-qubit Neutral Atom Simulator for Graph Classification
Edoardo Giusto, Gabriele Iurlaro, Bartolomeo Montrucchio +5
Neutral atom platforms are analogue quantum simulators that offer the possibility to map graphs onto a 2D qubit register using programmable Rubidium atoms arrays, whose valence ele…
Quantum Mpemba effect in chaotic systems with conservation laws
Thomas Martin Müller, Silvia Pappalardi, Rosario Fazio
Closed chaotic quantum systems relax after a quench into a Gibbs ensemble. At late times, the relaxation speed is determined by their conservation laws and hydrodynamics. As a resu…
Generalized stochastic spin-wave theory for open quantum spin systems
Zejian Li, Anna Delmonte, Rosario Fazio
We propose a semiclassical framework for solving open quantum dynamics in driven-dissipative spin systems. Our method consists of generalized spin-wave approximations tailored to d…
An Extensible Quantum Network Simulator Built on ns-3: Q2NS Design and Evaluation
Adam Pearson, Francesco Mazza, Marcello Caleffi +1
As quantum networking hardware remains costly and not yet widely accessible, simulation tools are essential for the design and evaluation of quantum network architectures and proto…
Complexity of Quantum Trajectories
Luca Lumia, Emanuele Tirrito, Mario Collura +2
Open quantum systems can be described by unraveling Lindblad master equations into ensembles of quantum trajectories. Here we investigate how the complexity of such trajectories is…
Operator delocalization in disordered spin chains via exact MPO marginals
Jonnathan Pineda, Mario Collura, Gianluca Passarelli +3
We investigate operator delocalization in disordered one-dimensional spin chains by introducing -- besides the already known operator mass -- a complementary measure of operator co…
Quantum Circuit-Based Adaptation for Credit Risk Analysis
Halima Giovanna Ahmad, Alessandro Sarno, Mehdi El Bakraoui +12
Noisy and Intermediate-Scale Quantum, or NISQ, processors are sensitive to noise, prone to quantum decoherence, and are not yet capable of continuous quantum error correction for f…
Operator Entanglement from Non-Commutative Symmetries
Michele Arzano, Goffredo Chirco
We argue that Hopf-algebra deformations of symmetries -- as encountered in non-commutative models of quantum spacetime -- carry an intrinsic content of th…
On the Emergence of Time and Space in Closed Quantum Systems
Tommaso Favalli
Time, space and entanglement are the main characters in this work. Their nature is still a great mystery in physics and we study here the possibility that these three phenomena are…
Nonadiabatic Self-Healing of Trotter Errors in Digitized Counterdiabatic Dynamics
Mara Vizzuso, Gianluca Passarelli, Giovanni Cantele +3
Trotter errors in digitized quantum dynamics arise from approximating time-ordered evolution under noncommuting Hamiltonian terms with a product formula. In the adiabatic regime, s…
Entanglement transition in unitary system-bath dynamics
Bo Xing, Giuliano Chiriacò, Paola Cappellaro +2
The evolution of a system coupled to baths is commonly described by a master equation that, in the long-time limit, yields a steady-state density matrix. However, when the same evo…
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…
Measurement-induced phase transition in interacting bosons from most likely quantum trajectory
Anna Delmonte, Zejian Li, Rosario Fazio +1
We propose a new theoretical method to describe the monitored dynamics of bosonic many-body systems based on the concept of the most likely trajectory. We show how such trajectory…
Classical and quantum chaotic synchronization in coupled dissipative time crystals
Eliška Postavová, Gianluca Passarelli, Procolo Lucignano +1
We investigate the dynamics of two coherently coupled dissipative time crystals. In the classical mean-field limit of infinite spin length, we identify a regime of chaotic synchron…
Detection of noise correlations in two qubit systems by Machine Learning
Dario Fasone, Shreyasi Mukherjee, Dario Penna +5
We introduce and validate a machine-learning assisted quantum sensing protocol to classify spatial and temporal correlations of classical noise affecting two ultrastrongly coupled…
QPing: a Quantum Ping Primitive for Quantum Networks
Jorge Miguel-Ramiro, Jessica Illiano, Francesco Mazza +5
We introduce the concept of Quantum Ping (QPing) as a diagnostic primitive for future quantum networks, designed to assess whether two or more end nodes can establish practical qua…
Quantum Paths: a Quantum Walk approach
Claudio Pellitteri, Marcello Caleffi, Angela Sara Cacciapuoti
The quantum switch, a process enabling a coherent superposition of different orders of quantum channels, has garnered significant attention due to its ability to enable noiseless c…
Polynomial-time Extraction of Entanglement Resources
Si-Yi Chen, Angela Sara Cacciapuoti, Marcello Caleffi
The extraction of EPR pairs and n-qubits GHZ states among remote nodes in quantum networks constitutes the resource primitives for end-to-end and on-demand communications. However,…
Quantum Fisher information as a witness of non-Markovianity and criticality in the spin-boson model
Daniele Parlato, Grazia Di Bello, Fabrizio Pavan +2
The quantum Fisher information, the quantum analogue of the classical Fisher information, is a central quantity in quantum metrology and quantum sensing due to its connection to pa…
Robustness of Magic in the quantum Ising chain via Quantum Monte Carlo tomography
Hari Timsina, Yi-Ming Ding, Emanuele Tirrito +5
We study the behavior of magic as a bipartite correlation in the quantum Ising chain across its quantum phase transition, and at finite temperature. In order to quantify the magic…
Data-Driven Reconstruction and Characterization of Stochastic Dynamics via Dynamical Mode Decomposition
Adva Baratz, Loris Maria Cangemi, Assaf Hamo +2
Noise fundamentally limits the performance and predictive capabilities of classical and quantum dynamical systems by degrading stability and obscuring intrinsic dynamical character…
Nonequilibrium thermometry via an ensemble of initially correlated qubits
Enrico Trombetti, Marco Malitesta, Marco Pezzutto +1
We investigate a nonequilibrium quantum thermometry protocol in which an ensemble of qubits, acting as temperature probes, is weakly coupled to a macroscopic thermal bath. The temp…
Spatial Leggett-Garg inequalities
Guillem Müller-Rigat, Donato Farina, Maciej Lewenstein +1
We formulate a spatial extension of the Leggett-Garg inequality by considering three distant observers locally measuring a many-body system at three subsequent times. The spatial f…
Complex orientation dependence of Casimir-Polder interaction induced by curvature and optical properties of the surface and the surrounding medium
Giuseppe Bimonte, Thorsten Emig
We employ a multiple scattering expansion to systematically derive curvature corrections to the Casimir-Polder (CP) interaction between small an-isotropic particles and general mag…
