Classification and transformations of quantum circuit decompositions for permutation operations
Ankit Khandelwal, Handy Kurniawan, Shraddha Aangiras +2
Efficient decomposition of permutation unitaries is vital as they frequently appear in quantum computing. In this paper, we identify the key properties that impact the decompositio…
Exploring the nonclassical dynamics of the "classical" Schrödinger equation
David Navia, Ángel S. Sanz
The introduction of nonlinearities in the Schrödinger equation has been considered in the literature as an effective manner to describe the action of external environments or mean…
Quantum squeezing via self-induced transparency in a photonic crystal fiber
M. S. Najafabadi, L. L. Sánchez-Soto, J. F. Corney +3
We study the quantum squeezing produced in self-induced transparency in a photonic crystal fiber by performing a fully quantum simulation based on the positive representation.…
Exotic Symmetry Breaking Properties of Self-Dual Fracton Spin Models
Giovanni Canossa, Lode Pollet, Miguel A. Martin-Delgado +2
Fracton codes host unconventional topological states of matter and are promising for fault-tolerant quantum computation due to their large coding space and strong resilience agains…
Check-Agnosia based Post-Processor for Message-Passing Decoding of Quantum LDPC Codes
Julien du Crest, Francisco Garcia-Herrero, Mehdi Mhalla +2
The inherent degeneracy of quantum low-density parity-check codes poses a challenge to their decoding, as it significantly degrades the error-correction performance of classical me…
Landau-Zener transition rates of superconducting qubits and absorption spectrum in quantum dots
Jorge G. Russo, Miguel Tierz
New exact formulas are derived for systems involving Landau-Zener transition rates and for absorption spectra in quantum dots. These rectify previous inaccurate approximations util…
Single-measurement Bell analysis
Alfredo Luis
We examine the satisfaction of Bell criteria for single realizations of quantum systems. This is possible via the joint noisy measurement of all observables involved in the Bell te…
Harnessing energy extracted from heat engines to charge quantum batteries
Debarupa Saha, Aparajita Bhattacharyya, Kornikar Sen +1
We explore the performance of three- and two-stroke heat engines with a qutrit working substance in charging two-level quantum batteries. We first classify the heat engines into tw…
Covariant operator bases for continuous variables
A. Z. Goldberg, A. B. Klimov, G. Leuchs +1
Coherent-state representations are a standard tool to deal with continuous-variable systems, as they allow one to efficiently visualize quantum states in phase space. Here, we work…
SQUWALS: A Szegedy QUantum WALks Simulator
Sergio A. Ortega, Miguel A. Martin-Delgado
Szegedy's quantum walk is an algorithm for quantizing a general Markov chain. It has plenty of applications such as many variants of optimizations. In order to check its properties…
Young's experiment with entangled bipartite systems: The role of underlying quantum velocity fields
A. S. Sanz
We consider the concept of velocity fields, taken from Bohmian mechanics, to investigate the dynamical effects of entanglement in bipartite realizations of Young's two-slit experim…
Coherence via reiterated beam splitting
Guillermo Díez, Laura Ares, Alfredo Luis
Beam splitters are not-free operations with regard to quantum coherence. As a consequence, they can create coherence from both coherent and incoherent states. We investigate the in…
Missing levels in intermediate spectra
María Hita-Pérez, Laura Muñoz, Rafael A. Molina
We derive an expression for the nearest-neighbor spacing distribution of the energy levels of quantum systems with intermediate dynamics between regularity and chaos and mis…
Relaxation time as a control parameter for exploring dynamical phase diagrams
Ángel L. Corps, Pedro Pérez-Fernández, Armando Relaño
We explore a full dynamical phase diagram by means of a double quench protocol that depends on a relaxation time as the only control parameter. The protocol comprises two fixed que…
Effects of the detection loophole on rival entanglement attestation techniques
Paranjoy Chaki, Kornikar Sen, Ujjwal Sen
Loopholes present in an experimental set-up can significantly affect the reliability of entanglement detection. We discuss two methods for detection of entanglement: one is by usin…
Two-qubit atomic gates: Spatio-temporal control of Rydberg interaction
Ignacio R. Sola, Vladimir S. Malinovsky, Jaewook Ahn +2
By controlling the temporal and spatial features of light, we propose a novel protocol to prepare two-qubit entangling gates on atoms trapped at close distance, which could potenti…
General theory for discrete symmetry-breaking equilibrium states
Ángel L. Corps, Armando Relaño
Spontaneous symmetry-breaking in phase transitions occurs when the system Hamiltonian is symmetric under a certain transformation, but the equilibrium states observed in nature are…
Discrete-time Semiclassical Szegedy Quantum Walks
Sergio A. Ortega, Miguel A. Martin-Delgado
Quantum walks are promising tools based on classical random walks, with plenty of applications such as many variants of optimization. Here we introduce the semiclassical walks in d…

Mario A. Quiroz-Juarez, Ángel L. Corps, Rafael A. Molina +4
We experimentally study the infinite-size limit of the Dicke model of quantum optics with a parity-breaking deformation strength that couples the system to an external bosonic rese…
Thermalization and dephasing in collisional reservoirs
Jorge Tabanera-Bravo, Juan M. R. Parrondo, Massimiliano Esposito +1
We introduce a wide class of quantum maps that arise in collisional reservoirs and are able to thermalize a system if they operate in conjunction with an additional dephasing mecha…
Experimental full network nonlocality with independent sources and strict locality constraints
Xue-Mei Gu, Liang Huang, Alejandro Pozas-Kerstjens +10
Nonlocality arising in networks composed of several independent sources gives rise to phenomena radically different from that in standard Bell scenarios. Over the years, the phenom…
