Spatially resolved photon statistics of general nanophotonic systems
Maksim Lednev, Diego Fernández de la Pradilla, Frieder Lindel +3
While experimental measurements of photon correlations have become routine in laboratories, theoretical access to these quantities for the light generated in complex nanophotonic d…
Efficient Eigenstate Preparation in an Integrable Model with Hilbert Space Fragmentation
Roberto Ruiz, Alejandro Sopena, Balázs Pozsgay +1
We consider the preparation of all the eigenstates of spin chains using quantum circuits. It is known that generic eigenstates of free-fermionic spin chains can be prepared with ci…
Optimal quantum algorithm for Gibbs state preparation
Cambyse Rouzé, Daniel Stilck França, Álvaro M. Alhambra
It is of great interest to understand the thermalization of open quantum many-body systems, and how quantum computers are able to efficiently simulate that process. A recently intr…
Genuine tripartite entanglement in graviton-matter interactions
Pablo Guillermo Carmona Rufo, Anupam Mazumdar, Carlos Sabín
We demonstrate the existence of genuine tripartite non-Gaussian entanglement in a quantum gravitational system formed by a quantum harmonic oscillator coupled to a single frequency…
Systematic construction of stabilizer codes via gauging abelian boundary symmetries
Bram Vancraeynest-De Cuiper, José Garre-Rubio
We propose a systematic framework to construct a (d+1)-dimensional stabilizer model from an initial generic d-dimensional abelian symmetry. Our approach builds upon the iterative g…
Digital quantum simulation of cosmological particle creation with IBM quantum computers
Marco Díaz Maceda, Carlos Sabín
We use digital quantum computing to simulate the creation of particles in a dynamic spacetime. We consider a system consisting of a minimally coupled massive quantum scalar field i…
Cavity Control of Topological Qubits: Fusion Rule, Anyon Braiding, and Majorana-Schrödinger Cat States
Luis Quiroga, Fernando J. Gómez-Ruiz, Ivan A. Bocanegra-Garay +2
We investigate the effects of coupling a local electromagnetic cavity to a segment of a topological Kitaev chain (KC), with particular emphasis on the interplay between photons and…
Absolute dimensionality of quantum ensembles
Alexander Bernal, Gabriele Cobucci, Martin J. Renner +1
The dimension of a quantum state is traditionally seen as the number of superposed distinguishable states in a given basis. We propose an absolute, i.e.~basis-independent, notion o…
Constructing the spin-1 Haldane phase on a qudit quantum processor
C. L. Edmunds, E. Rico, I. Arrazola +4
Symmetry-protected topological phases have fundamentally changed our understanding of quantum matter. An archetypal example of such a quantum phase of matter is the Haldane phase,…
Error threshold in active steering protocols for few-qubit systems
Nico Ackermann, Samuel Morales, Alfredo Levy Yeyati +2
We study active steering protocols for weakly measured qubits in the presence of error channels due to amplitude and phase noise. If the error rate is sufficiently small, the proto…
Correlations in Circular Quantum Cascades
Miguel Ángel Palomo Marcos, Eduardo Zubizarreta Casalengua, Elena del Valle +1
We introduce a one-way, one-quantum cascade, whereby a single excitation proceeds one-directionwise in a ladder of energy levels. This makes a variation from more famous two-way ca…
Quantum noise modeling through Reinforcement Learning
Simone Bordoni, Andrea Papaluca, Piergiorgio Buttarini +3
In the current era of quantum computing, robust and efficient tools are essential to bridge the gap between simulations and quantum hardware execution. In this work, we introduce a…

Jaime Abad-Arredondo, Antonio I. Fernández-Domínguez
We provide a comprehensive study of the capabilities of modulated electron wavefunctions for the preparation and readout of the quantum state of the quantum emitters (QEs) they int…
Towards Photon-Number-Encoded High-dimensional Entanglement from a Sequentially Excited Quantum Three-Level System
Daniel A. Vajner, Nils D. Kewitz, Martin von Helversen +9
The sequential resonant excitation of a 2-level quantum system results in the emission of a state of light showing time-entanglement encoded in the photon-number-basis - notions th…
General theory of cavity-mediated interactions between low-energy matter excitations
Carlos J. Sánchez Martínez, Frieder Lindel, Francisco J. García-Vidal +1
The manipulation of low-energy matter properties such as superconductivity, ferromagnetism and ferroelectricity via cavity quantum electrodynamics engineering has been suggested as…
Regular language quantum states
Marta Florido-Llinàs, Álvaro M. Alhambra, David Pérez-García +1
We introduce regular language states, a family of quantum many-body states. They are built from a special class of formal languages, called regular, which has been thoroughly studi…
Entanglement of photonic modes from a continuously driven two-level system
Jiaying Yang, Ingrid Strandberg, Alejandro Vivas-Viana +7
The ability to generate entangled states of light is a key primitive for quantum communication and distributed quantum computation. Continuously driven sources, including those bas…
Long-range interactions in Weyl dense atomic arrays protected from dissipation and disorder
Iñaki García-Elcano, Paloma A. Huidobro, Jorge Bravo-Abad +1
Long-range interactions are a key resource in many quantum phenomena and technologies. Free-space photons mediate power-law interactions but lack tunability and suffer from decoher…
Asymmetries of thermal processes in open quantum systems
Álvaro Tejero, Rafael Sánchez, Laiachi El Kaoutit +2
An intriguing phenomenon in non-equilibrium quantum thermodynamics is the asymmetry of thermal processes. Relaxation to thermal equilibrium is the most important dissipative proces…
