Certification of non-classicality in all links of a photonic star network without assuming quantum mechanics
Ning-Ning Wang, Alejandro Pozas-Kerstjens, Chao Zhang +6
Networks composed of independent sources of entangled particles that connect distant users are a rapidly developing quantum technology and an increasingly promising test-bed for fu…
Can we observe non-perturbative vacuum shifts in cavity QED?
Rocío Sáez-Blázquez, Daniele de Bernardis, Johannes Feist +1
We address the fundamental question whether or not it is possible to achieve conditions under which the coupling of a single dipole to a strongly confined electromagnetic vacuum ca…
Vacuum-field-induced state mixing
Diego Fernández de la Pradilla, Esteban Moreno, Johannes Feist
By engineering the electromagnetic vacuum field, the induced Casimir-Polder shift (also known as Lamb shift) and spontaneous emission rates of individual atomic levels can be contr…
Non-Hermitian Anharmonicity Induces Single-Photon Emission
Anael Ben-Asher, Antonio I. Fernández-Domínguez, Johannes Feist
Single-photon sources are in high demand for quantum information applications. A paradigmatic way to achieve single-photon emission is through anharmonicity in the energy levels, s…
Resource frugal optimizer for quantum machine learning
Charles Moussa, Max Hunter Gordon, Michal Baczyk +3
Quantum-enhanced data science, also known as quantum machine learning (QML), is of growing interest as an application of near-term quantum computers. Variational QML algorithms hav…
Inflation: a Python library for classical and quantum causal compatibility
Emanuel-Cristian Boghiu, Elie Wolfe, Alejandro Pozas-Kerstjens
We introduce Inflation, a Python library for assessing whether an observed probability distribution is compatible with a causal explanation. This is a central problem in both theor…
Accelerating the training of single-layer binary neural networks using the HHL quantum algorithm
Sonia Lopez Alarcon, Cory Merkel, Martin Hoffnagle +2
Binary Neural Networks are a promising technique for implementing efficient deep models with reduced storage and computational requirements. The training of these is however, still…
Two-photon emission in detuned resonance fluorescence
Eduardo Zubizarreta Casalengua, Elena del Valle, Fabrice P. Laussy
We discuss two-photon correlations from the side peaks that are formed when a two-level system emitter is driven coherently, with a detuning between the driving source and the emit…
Probing and harnessing photonic Fermi arc surface states using light-matter interactions
Iñaki García-Elcano, Jaime Merino, Jorge Bravo-Abad +1
Fermi arcs, i.e., surface states connecting topologically-distinct Weyl points, represent a paradigmatic manifestation of the topological aspects of Weyl physics. Here, we investig…
Classical simulation of short-time quantum dynamics
Dominik S. Wild, Álvaro M. Alhambra
Recent progress in the development of quantum technologies has enabled the direct investigation of dynamics of increasingly complex quantum many-body systems. This motivates the st…
Parrondo's paradox for discrete-time quantum walks in momentum space
Georg Trautmann, Caspar Groiseau, Sandro Wimberger
We investigate the possibility of implementing a sequence of quantum walks whose probability distributions give an overall positive winning probability, while it is negative for th…
Suppressing Amplitude Damping in Trapped Ions: Discrete Weak Measurements for a Non-unitary Probabilistic Noise Filter
Andrea Rodriguez-Blanco, K. Birgitta Whaley, Alejandro Bermudez
The idea of exploiting maximally-entangled states as a resource lies at the core of several modalities of quantum information processing, including secure quantum communication, qu…
Nonlinear Interferometry for Quantum-Enhanced Measurements of Multiphoton Absorption
Shahram Panahiyan, Carlos Sánchez Muñoz, Maria V. Chekhova +1
Multiphoton absorption is of vital importance in many spectroscopic, microscopic or lithographic applications. However, given that it is an inherently weak process, the detection o…
Depletion in fermionic chains with inhomogeneous hoppings
Begoña Mula, Nadir Samos Sáenz de Buruaga, Germán Sierra +2
The ground state of a free-fermionic chain with inhomogeneous hoppings at half-filling can be mapped into the Dirac vacuum on a static curved space-time, which presents exactly hom…
Analogue non-causal Null Curves and Chronology protection in a dc-SQUID Array
Carlos Sabín
We propose an analogue quantum simulator of a 1+1 D spacetime containing non-causal curves,in particular, null geodesics going back in time, by means of a dc-SQUID array embedded o…
Interaction between giant atoms in a one-dimensional structured environment
Ariadna Soro, Carlos Sánchez Muñoz, Anton Frisk Kockum
Giant atoms -- quantum emitters that couple to light at multiple discrete points -- are emerging as a new paradigm in quantum optics thanks to their many promising properties, such…
Entanglement links and the quasiparticle picture
Silvia N. Santalla, Giovanni Ramírez, Sudipto Singha Roy +2
The time evolution of a quantum state with short-range correlations after a quench to a one-dimensional critical Hamiltonian can be understood using the quasi-particle picture, whi…
Spontaneous Scattering of Raman Photons from Cavity-QED Systems in the Ultrastrong Coupling Regime
Vincenzo Macrì, Alberto Mercurio, Franco Nori +2
