Beam splitter as quantum coherence-maker

L Ares, A Luis - Physica Scripta, 2022 - iopscience.iop.org
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 …

Photonic Entanglement and Polarization Nonclassicality: Two Manifestations, One Nature

L Ares, N Prasannan, E Agudelo, A Luis… - arXiv preprint arXiv …, 2024 - arxiv.org
We demonstrate in theory and experiment the strict equivalence between nonclassical
polarization and the entanglement of indistinguishable photons, thereby unifying these two …

Characterizing nonclassical correlation via local channels

M Rajendran, S Balakrishnan - Physica Scripta, 2024 - iopscience.iop.org
Local operation is an important tool to characterize the nonlocal aspects of multipartite
quantum system. Exploiting the notion of resource theory of coherence, in this article, we …

Coherence and incoherence in quadrature basis

L Ares, A Luis - arXiv preprint arXiv:2307.08333, 2023 - arxiv.org
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 …

Unification of nonclassical signatures under the concept of quantum coherence

L Ares Santos - 2024 - docta.ucm.es
Quantum theory is one of the most fascinating proposals that physics has ever made. Behind
its extremely accurate precision in predicting the behaviour of nature, surprisingly, one finds …
