Currículum

Currículum breu

R. Zambrini's research activity started during her Master Thesis (1999) with Prof. L.Lugiato within EU project QUSTRUCT focusing on spatial multimode quantum phenomena in optics. In 2003 she obtained the PhD degree at UIB under the supervision of Prof. M. San Miguel, deepening her knowledge of complex phenomena such as spatial instabilities and spontaneous pattern formation in nonlinear optics, addressing both classical and quantum aspects and acquiring skills on statistical physics, master equations formalism, quasi-probability description of quantum mechanics and numerical simulation of stochastic partial differential equations. From 2003 to 2006 she joined the CNQO group lead by Prof. S.M. Barnett at Strathclyde University (Glasgow, UK) and worked on the orbital angular momentum of light (project "Multi-dimensional quantum entanglement and high density information transfer").

In 2005 she has been awarded of a Ramon y Cajal fellowship, joining IFISC in 2006 and from 2008 she is 'Científico Titular' of CSIC. Her main results in the first phase of her career have been the first fully multimode analysis of quantum fluctuations associated to optical patterns, the description of their non-classical signatures (squeezing and quantum correlations) and addressing fundamental questions on mechanical properties of light (mainly spin and orbital angular momenta, PRL2006). She has also independently collaborated with Dr. F. Papoff on classical two-point non-locality in extended systems with feedback demonstrating their potential in developing convective instabilities and unusual signal splittings (PRL2005 and 07). An important result in the same period has been the role of photonic crystals inhibiting spatial instabilities in broad area optical devices (PRL2004).

From 2006 she carries on research at IFISC on Quantum Complex Systems. She has fruitful collaborations with Dr. Fernando Galve (IFISC), Dr. Gian-Luca Giorgi (IFISC) and several international partnerships. One main topics of interest in these last years has been the quantum-to-classical transition focusing on a recently introduced indicator of quantum correlations, the discord. Main contributions have been the demonstration of relative constraints between the maximum discord for a given classical correlation (maximally discordant states in PRA11), the identification of gates producing the maximum discord when applied to classical states (discording power in PRL2013) and the definition of genuine quantum correlations in multipartite systems (PRL2011).

A second topics bridges quantum information approaches and the study of complex phenomena. With particular interest on collective phenomena and quantum synchronization. After a first demonstration in linear systems under proper decoherence conditions in 2011, the richness of this phenomenon has been fully shown in quantum networks (SciRep2013): main results are the presence of robust quantum signatures accompanying synchronization, the possibility to tune a network (or a cluster) into a fully synchronized state by local tuning and the possibility to entangle separate oscillators through a network when engineering the plugging. This phenomenon is explored in experimental platforms including optomechanical oscillators [NJP2017] and atoms. The studies of extended systems is central to future research on microscopic descriptions of open systems to characterize decoherence in complex environments, the quantum to classical transition as in quantum Darwinism, memory effects, and quantum probes [SciRep2017].

Recently she has been PI of a H2020 project (QUPROCS) and two national ones. A recently submitted proposal to QUANTERA received excellent evaluations, even if finally was not selected; further proposals are being submitted to the Quantum Technologies Flagship. She is also part of the excellence network RICTE.
