Extending the Bloch sphere model to an N-qubit system
Francisco Piñero, Cristian Franco, Hernán I. de la Cruz +5
The Bloch sphere is an elegant tool for representing single-qubit states. However, a widely accepted generalization for multi-qubit systems with entanglement remains absent. We pro…
Photon position eigenstates in configuration space
Artemio González-López, Luis Martínez Alonso
The expressions of the eigenfunctions of the Hawton photon position operator in configuration space are derived for several classes of wave function, including the Riemann--Silbers…
Decoherence in matter-wave Talbot interference: A hydrodynamic probability-flow analysis
David Navia, Ángel S. Sanz
We investigate the suppression of matter-wave Talbot interference under environmentally induced decoherence. The system is modeled as an atomic beam diffracted by a periodic gratin…
Spectroscopy of the Dirac oscillator perturbed by a surface delta potential
J. Munárriz, F. Domínguez-Adame, R. P. A. Lima
We study theoretically the level shift of the Dirac oscillator perturbed by any sharply peaked potential approaching a surface delta potential. A Green function method is used to o…
Benchmarking quantum phase-space methods for near-resonant light propagation
Mojdeh S. Najafabadi, Joel F. Corney, Luis Sanchez Soto +1
We study the dynamics of light interacting with a near-resonant atomic medium using the truncated Wigner and positive P phase-space representations. The atomic degrees of freedom a…
Experimental characterization of the hierarchy of quantum correlations in top quark pairs
Yoav Afik, Regina Demina, Alan Herrera +3
Recent results from the Large Hadron Collider have demonstrated quantum entanglement of top quark-antiquark pairs using the spin degrees of freedom. Based on the doubly differentia…
From Superradiance to Superabsorption: An Exact Treatment of Non-Markovian Cooperative Radiation
Ignacio González, Ángel Rivas
We investigate the emergence of cooperative radiation phenomena in ensembles of two-level atoms coupled to a lossy resonant cavity beyond the Markovian and mean-field approximation…
Chaos, thermalization and breakdown of quantum-classical correspondence in a collective many-body system
Ángel L. Corps, Sebastián Gómez, Pavel Stránský +2
We investigate thermalization and the quantum-classical correspondence in the collective Bose-Hubbard model, focusing on the four-site case. Our analysis of the classical phase-spa…
Error Resilience of Fracton Codes and Near Saturation of Code-Capacity Threshold in Three Dimensions
Giovanni Canossa, Lode Pollet, Miguel A. Martin-Delgado +2
Fracton codes have been intensively studied as novel topological states of matter, yet their fault-tolerant properties remain largely unexplored. Here, we investigate the optimal t…
Local fermion density in inhomogeneous free-fermion chains: a discrete WKB approach
Martín Zapata, Federico Finkel, Artemio González-López
We introduce a novel analytical approach for studying free-fermion (XX) chains with smoothly varying, site-dependent hoppings and magnetic fields. Building on a discrete WKB-like a…
Modified logarithmic Sobolev inequalities for CSS codes
Sebastian Stengele, Ángela Capel, Li Gao +5
We consider the class of Davies quantum semigroups modelling thermalization for translation-invariant Calderbank-Shor-Steane (CSS) codes in D dimensions. We prove that conditions o…
Generalised fractional Rabi problem
Alexander Lopez, Sébastien Fumeron, Malte Henkel +2
Fractional quantum dynamics provides a natural framework to capture nonlocal temporal behavior and memory effects in quantum systems. In this work, we analyze the physical conseque…
Phenomenological Noise Models and Optimal Thresholds of the 3D Toric Code
Ji-Ze Xu, Yin Zhong, Miguel A. Martin-Delgado +2
Three-dimensional (3D) topological codes offer the advantage of supporting fault-tolerant implementations of non-Clifford gates, yet their performance against realistic noise remai…
Decoding Correlated Errors in Quantum LDPC Codes
Arshpreet Singh Maan, Francisco-Garcia Herrero, Alexandru Paler +1
We introduce a decoding framework for correlated errors in quantum LDPC codes under circuit-level noise. The core of our approach is a graph augmentation and rewiring for interfere…
Efficient and simple Gibbs state preparation of the 2D toric code via duality to classical Ising chains
Pablo Páez-Velasco, Niclas Schilling, Samuel O. Scalet +2
We introduce the notion of polynomial-depth duality transformations, which relates two sets of operator algebras through a conjugation by a poly-depth quantum circuit, and make use…
Hybrid Reward-Driven Reinforcement Learning for Efficient Quantum Circuit Synthesis
Sara Giordano, Kornikar Sen, Miguel A. Martin-Delgado
A reinforcement learning (RL) framework is introduced for the efficient synthesis of quantum circuits that generate specified target quantum states from a fixed initial state, addr…
Impact of quadrature measurement on quantum coherence
Lucía Álvarez, Alfredo Luis
We examine the behavior of quadrature coherence under the measurement of the same field quadrature. This is carried out with the help of a beam splitter, which implies the contribu…
Time Crystal from Self-Amplification of Spontaneous Analog Hawking Radiation
Juan Ramón Muñoz de Nova, Fernando Sols
We propose a time crystal based on a quantum black-hole laser, where the genuinely spontaneous character of the symmetry breaking stems from the self-amplification of spontaneous H…
Unbounded entanglement-sustaining sequential local quantum state discrimination
Debarupa Saha, Priya Ghosh, Kornikar Sen +2
Two pure orthogonal quantum states can be perfectly distinguished by sequential local action of multiple pairs of parties. However, this process typically leads to the complete dis…
