Anna Sanpera

Universitat Autònoma de Barcelona

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, first as a research fellow and then as 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 interest are Quantum Information, Atomic Physics and more recently Condensed Matter Physics. I 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 exotic properties are difficult to understand. 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 engineer more powerful ways to process and distribute information and build, in a near future, a quantum computers and simulators able to perform tasks that classical computers cannot. I am also working in Quantum Thermometry, Quantum Learning and Quantum Metrology to exploit 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.
