Photon liquefaction in time
Eduardo Zubizarreta Casalengua, Elena del Valle, Fabrice P. Laussy
We provide a mechanism to imprint local temporal correlations in photon streams which have the same character as spatial correlations in liquids. Usual single-photon emitters corre…
Phonon-photon conversion as mechanism for cooling and coherence transfer
Alessandro Ferreri, David Edward Bruschi, Frank K. Wilhelm +2
The dynamical Casimir effect is the physical phenomenon where the mechanical energy of a movable wall of a cavity confining a quantum field can be converted into quanta of the fiel…
Frequency-resolved Purcell effect for the dissipative generation of steady-state entanglement
Alejandro Vivas-Viaña, Diego Martín-Cano, Carlos Sánchez Muñoz
We report a driven-dissipative mechanism to generate stationary entangled states among strongly-interacting quantum emitters placed within a cavity. Driving the ensemble into t…
Electrostatic nature of cavity-mediated interactions between low-energy matter excitations
Petros-Andreas Pantazopoulos, Johannes Feist, Akashdeep Kamra +1
The use of cavity quantum electrodynamical effects, i.e., of vacuum electromagnetic fields, to modify material properties in cavities has rapidly gained popularity and interest in…
On the categorical foundations of quantum information theory: Categories and the Cramer-Rao inequality
Florio M. Ciaglia, Fabio Di Cosmo, Laura González-Bravo +2
An extension of Cencov's categorical description of classical inference theory to the domain of quantum systems is presented. It provides a novel categorical foundation to the theo…
The Bethe Ansatz as a Quantum Circuit
Roberto Ruiz, Alejandro Sopena, Max Hunter Gordon +2
The Bethe ansatz represents an analytical method enabling the exact solution of numerous models in condensed matter physics and statistical mechanics. When a global symmetry is pre…
Entanglement and entropy in multipartite systems: a useful approach
A. Bernal, J. A. Casas, J. M. Moreno
Quantum entanglement and quantum entropy are crucial concepts in the study of multipartite quantum systems. In this work we show how the notion of concurrence vector, re-expressed…
Matrix product state approximations to quantum states of low energy variance
Kshiti Sneh Rai, J. Ignacio Cirac, Álvaro M. Alhambra
We show how to efficiently simulate pure quantum states in one dimensional systems that have both finite energy density and vanishingly small energy fluctuations. We do so by study…
Dissipative stabilization of maximal entanglement between non-identical emitters via two-photon excitation
Alejandro Vivas-Viaña, Diego Martín-Cano, Carlos Sánchez Muñoz
Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement. In V…
A Lindblad master equation capable of describing hybrid quantum systems in the ultra-strong coupling regime
Maksim Lednev, Francisco J. García-Vidal, Johannes Feist
Despite significant theoretical efforts devoted to studying the interaction between quantized light modes and matter, the so-called ultra-strong coupling regime still presents sign…
Classical analogs of generalized purities, entropies, and logarithmic negativity
Bogar Díaz, Diego González, Marcos J. Hernández +1
It has recently been proposed classical analogs of the purity, linear quantum entropy, and von Neumann entropy for classical integrable systems, when the corresponding quantum syst…
Single-photon source over the terahertz regime
Caspar Groiseau, Antonio I. Fernández-Domínguez, Diego Martín-Cano +1
We present a proposal for a tunable source of single photons operating in the terahertz (THz) regime. This scheme transforms incident visible photons into quantum THz radiation by…
Synthetic gauge theories based on parametric excitations of trapped ions
O. Băzăvan, S. Saner, E. Tirrito +3
We present a detailed scheme for the analog quantum simulation of gauge theories in crystals of trapped ions, which exploits a more efficient hybrid encoding of the…
Thermal masses and trapped-ion quantum spin models: a self-consistent approach to Yukawa-type interactions in the model
Pablo Viñas Martínez, Esperanza López, Alejandro Bermudez
The quantum simulation of magnetism in trapped-ion systems makes use of the crystal vibrations to mediate pairwise interactions between spins, which are encoded in the internal ele…
Multipartite entanglement encoded in the photon-number basis by sequential excitation of a three-level system
Alan C. Santos, Christian Schneider, Romain Bachelard +2
We propose a general scheme to generate entanglement encoded in the photon-number basis, via a sequential resonant two-photon excitation of a three-level system. We apply it to the…
Bell inequalities with overlapping measurements
Moisés Bermejo Morán, Alejandro Pozas-Kerstjens, Felix Huber
Which nonlocal correlations can be obtained, when a party has access to more than one subsystem? While traditionally nonlocality deals with spacelike separated parties, this questi…
Resonance fluorescence of two asymmetrically pumped and coupled two-level systems
C. A. Downing, E. del Valle, A. I. Fernández-Domínguez
We study a driven-dissipative duo of two-level systems in an open quantum systems approach, modelling a pair of atoms or (more generally) meta-atoms. Allowing for complex-valued co…
Ultra-bright single photon source based on an atomically thin material
Jens-Christian Drawer, Victor Nikolaevich Mitryakhin, Hangyong Shan +15
Solid-state single photon sources are central building blocks in quantum communication networks and on-chip quantum information processing. Atomically thin crystals were establishe…
Digital quantum simulation of quantum gravitational entanglement with IBM quantum computers
Carlos Sabín
We report the digital quantum simulation of a hamiltonian involved in the generation of quantum entanglement by gravitational means. In particular, we focus on a pair of quantum ha…
About the quantum Talbot effect on the sphere
Fernando Chamizo, Osvaldo Santillan
The Schrödinger equation on a circle with an initially localized profile of the wave function is known to give rise to revivals or replications, where the probability density of th…
Effects of noise on the overparametrization of quantum neural networks
Diego García-Martín, Martin Larocca, M. Cerezo
Overparametrization is one of the most surprising and notorious phenomena in machine learning. Recently, there have been several efforts to study if, and how, Quantum Neural Networ…
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…
