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…
Phase-space quantum Wiener-Khintchine theorem
Ainara Álvarez-Marcos, Alfredo Luis
We derive a quantum version of the classical-optics Wiener-Khintchine theorem within the framework of detection of phase-space displacements with a suitably designed quantum ruler.…
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…
