Quantum entanglement vs classical communication to play XOR games
Abstract: A primary objective in quantum information theory is to identify situations in which quantum entanglement exhibits significantly greater power than classical resources. Although the transmission of classical information is undeniably a potent resource for classical games, the extent of its power in playing quantum games is not immediately evident. This presentation will focus on XOR games in both classical and quantum contexts, exploring the comparison between the efficacy of quantum entanglement and classical information in playing these games.
Bio: Carlos Palazuelos earned his M.Sc. and Ph.D. degrees in mathematics from the Universidad Complutense de Madrid, Madrid, Spain, in 2004 and 2009, respectively. Following a post-doctoral position at the University of Illinois at Urbana-Champaign, USA, in 2010, where he served as a Visiting Assistant Professor, he joined the Consejo Superior de Investigaciones Cientificas (CSIC), Spain, in 2011, under a "Juan de la Cierva" contract. After three years, he secured a "Ramón y Cajal" contract and became part of the Mathematical Analysis Department at the Universidad Complutense de Madrid. In 2019, he was appointed as an Assistant Professor. His research focuses on various aspects of functional analysis and quantum information theory, including operator algebras and operator spaces, Bell inequalities and nonlocal games, entanglement theory, and quantum channel capacities.
