Limited path entanglement percolation in quantum complex networks
Martí Cuquet, John Calsamiglia
We study entanglement distribution in quantum complex networks where nodes are connected by bipartite entangled states. These networks are characterized by a complex structure, whi…
Fast and robust quantum computation with ionic Wigner crystals
J. D. Baltrusch, A. Negretti, J. M. Taylor +1
We present a detailed analysis of the modulated-carrier quantum phase gate implemented with Wigner crystals of ions confined in Penning traps. We elaborate on a recent scheme, prop…
Quantum-noise quenching in atomic tweezers
Stefano Zippilli, Bernd Mohring, Eric Lutz +2
The efficiency of extracting single atoms or molecules from an ultracold bosonic reservoir is theoretically investigated for a protocol based on lasers, coupling the hyperfine stat…
Multi-copy programmable discrimination of general qubit states
G. Sentís, E. Bagan, J. Calsamiglia +1
Quantum state discrimination is a fundamental primitive in quantum statistics where one has to correctly identify the state of a system that is in one of two possible known states.…
Gapped Two-Body Hamiltonian for continuous-variable quantum computation
Leandro Aolita, Augusto J. Roncaglia, Alessandro Ferraro +1
We introduce a family of Hamiltonian systems for measurement-based quantum computation with continuous variables. The Hamiltonians (i) are quadratic, and therefore two body, (ii) a…
Quantum jumps induced by the center-of-mass motion of a trapped atom
J. M. Torres, M. Bienert, S. Zippilli +1
We theoretically study the occurrence of quantum jumps in the resonance fluorescence of a trapped atom. Here, the atom is laser cooled in a configuration of level such that the occ…
Optimal quantum estimation of the Unruh-Hawking effect
Mariona Aspachs, Gerardo Adesso, Ivette Fuentes
We address on general quantum-statistical grounds the problem of optimal detection of the Unruh-Hawking effect. We show that the effect signatures are magnified up to potentially o…
Transferring orbital and spin angular momenta of light to atoms
Antonio Picón, Albert Benseny, Jordi Mompart +4
Light beams carrying orbital angular momentum, such as Laguerre-Gaussian beams, give rise to the violation of the standard dipolar selection rules during the interaction with matte…
Implementation of a three-qubit quantum error correction code in a cavity-QED setup
Carlo Ottaviani, David Vitali
The correction of errors is of fundamental importance for the development of contemporary computing devices and of robust communication protocols. In this paper we propose a scheme…
Local discrimination of mixed states
J. Calsamiglia, J. I. de Vicente, R. Munoz-Tapia +1
We provide rigorous, efficiently computable and tight bounds on the average error probability of multiple-copy discrimination between qubit mixed states by Local Operations assiste…
Zero-error communication via quantum channels, non-commutative graphs and a quantum Lovasz theta function
Runyao Duan, Simone Severini, Andreas Winter
We study the quantum channel version of Shannon's zero-error capacity problem. Motivated by recent progress on this question, we propose to consider a certain operator space as the…
Progress toward scalable tomography of quantum maps using twirling-based methods and information hierarchies
Cecilia C. López, Ariel Bendersky, Juan Pablo Paz +1
We present in a unified manner the existing methods for scalable partial quantum process tomography. We focus on two main approaches: the one presented in Bendersky et al. [Phys. R…
Cold-Atom-Induced Control of an Optomechanical Device
M. Paternostro, G. De Chiara, G. M. Palma
We consider a cavity with a vibrating end mirror and coupled to a Bose-Einstein condensate. The cavity field mediates the interplay between mirror and collective oscillations of th…
Structural defects in ion crystals by quenching the external potential: the inhomogeneous Kibble-Zurek mechanism
A. del Campo, G. De Chiara, G. Morigi +2
The non-equilibrium dynamics of an ion chain in a highly anisotropic trap is studied when the transverse trap frequency is quenched across the value at which the chain undergoes a…
Adiabatic Markovian Dynamics
Ognyan Oreshkov, John Calsamiglia
We propose a theory of adiabaticity in quantum Markovian dynamics based on a decomposition of the Hilbert space induced by the asymptotic behavior of the Lindblad semigroup. A cent…
Ion-trap simulation of the quantum phase transition in an exactly solvable model of spins coupled to bosons
Gian Luca Giorgi, Simone Paganelli, Fernando Galve
It is known that arrays of trapped ions can be used to efficiently simulate a variety of many-body quantum systems. Here, we show how it is possible to build a model representing a…
Engineering Atomic Quantum Reservoirs for Photons
Susanne Pielawa, Luiz Davidovich, David Vitali +1
We present protocols for creating entangled states of two modes of the electromagnetic field, by using a beam of atoms crossing microwave resonators. The atoms are driven by a tran…
