Experimental Sciences & Mathematics

I graduated at Universitat Autònoma de Barcelona in 1986. From 1988-1992 Ph.D fellow (FPI) from the Ministerio de Educación y Ciencia at the Universitat Autònoma de Barcelona. In 1993, I moved to the University of Oxford, as research fellow and I obtained a Fleming fellowship. In 1996, I moved to Saclay (Paris) as an European Post-Doctoral Research Fellow. In 1998 I was appointed research fellow at the Leibninz University, in Hannover (Germany) where I did my habilitation and became Professor Assistant. Since 2005 I am an ICREA Research Professor. My research interests are quite interdisciplinary and range from quantum information theory, to quantum gases and more recently condensed matter. Presently, I am working in the interface between quantum information and condensed matter. I have stable collaborations with different research groups both at national and international level. Otherwise I am fond of literature, sports and children.

Research interests

My research belongs to the area of Quantum Information, Atomic Physics and more recently Condensed Matter Physics. On one hand, we study the properties that atoms frozen to very low temperatures display. Ultracold atomic gases permit to study, in a very clean way, a rich variety of systems which appear in Nature but whose properties are very difficult to observe and understand. On the other hand, I am also involved in the mathematical description of entanglement, arguably the most distinct feature of quantum physics. Taking advantage of the quantum properties of matter, we can engineer more powerful ways to process and distribute information and build, in a near future, a quantum computer able to perform tasks that a classical computer cannot. I have initiated a new research line in my group “Quantum Thermometry” within a STREP Europen Project and I am starting to work in “Quantum learning” and “Quantum sensing” to explot the advantatges quantum physics offers us to improve machine learning tasks as well as the determination of unknown parameters with a precission that classical physics cannot achieve.
