Coherence and incoherence in quadrature basis
Laura Ares, Alfredo Luis
How to manage coherence as a continuous variable quantum resource is still an open question. We face this situation from the very definition of incoherent states in quadrature basi…
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…
Beam splitter as quantum coherence-maker
Laura Ares, Alfredo Luis
The aim of this work is to answer the question of how much quantum coherence a beam splitter is able to produce. To this end we consider as the variables under study both the amoun…
Distance-based approach to quantum coherence and nonclassicality
Laura Ares, Alfredo Luis
We provide a coherence-based approach to nonclassical behavior by means of distance measures. We develop a quantitative relation between coherence and nonclassicality quantifiers,…
Coherence, nonclassicality and metrological resolution
Laura Ares, Alfredo Luis
We demonstrate the simple and deep equivalence between quantum coherence and nonclassicality and the definite way in which they determine metrological resolution. Moreover, we defi…
Inequalities for complementarity in observed statistics
Elisa Masa, Laura Ares, Alfredo Luis
We provide an analysis of complementarity via a suitably designed classicalmodel that leads to a set of inequalities that can be tested by means ofunsharp measurements. We show tha…
Quantum metrology and coherence
Laura Ares, Alfredo Luis
We address the relation between quantum metrological resolution and coherence. We examine this dependence in two manners: we develop a quantum Wiener-Kintchine theorem for a suitab…
Violation of Bell quantum probability inequalities with classical fields
Laura Ares, Alfredo Luis
Violations of Bell inequalities in classical optics have been demonstrated in terms of field mean intensities and correlations, however, the quantum meaning of violations point to…
Observed quantum dynamics: classical dynamics and lack of Zeno effect
Julián López, Laura Ares, Alfredo Luis
We examine a case study where classical evolution emerges when observing a quantum evolution. By using a single-mode quantum Kerr evolution interrupted by measurement of the double…
Number-phase entanglement and Einstein-Podolsky-Rosen steering
Matteo Fadel, Laura Ares, Alfredo Luis +1
We use the uncertainty relation between the operators associated to the total number of particles and to the relative phase of two bosonic modes to construct entanglement and Einst…
Nonclassical joint distributions and Bell measurements
Elisa Masa, Laura Ares, Alfredo Luis
Derivation and experimental violation of Bell-like inequalities involve the measurement of in-compatible observables. Simple complementarity forbids the existence of such joint pro…
Classical and quantum complementarity
Raquel Galazo, Irene Bartolomé, Laura Ares +1
Two complementary observables can be measured simultaneously so that the exact individual distributions can be recovered by a proper data inversion. We apply this program to the pa…
Phase space quantum-classical hybrid model
Gerardo García, Laura Ares, Alfredo Luis
In this work we provide a complete model of semiclassical theories by including back-reaction and correlation into the picture. We specially aim at the interaction between light an…
