DIPC Colloquium: New frontiers in quantum optics and quantum information In the last years, quantum optics and quantum information have merged with other areas of science, like condensed matter or high-energy physics. This opens up various scientific questions and poses new theoretical challenges. In this talk I will give a brief overview of some of the areas of research that have emerged in that context, like the study and applications of emitters close to structured baths, and the development of theoretical tools to address many-body quantum problems. In the first case, I will describe the appearance of new of many-photon bound states, the preparation of Fock states, the simulation of long-range spin interacting models, or the observation of exotic features in collective decays. In the second, I will briefly describe the connections with condensed matter theory problems. _[Ignacio Cirac](http://www2.mpq.mpg.de/Theorygroup/CIRAC/wiki/index.php/Prof._Dr._J.Ignacio_Cirac.html) is a theoretical physicist who works in quantum optics, quantum information, and quantum many-body physics. In his research he proposes experiments to demonstrate and investigate interesting quantum effects, contributes to the theory of quantum information, and he applies the methods developed there to address problems in condensed-matter and particle physics. He is best known for his ground-breaking proposals to realize quantum computers and quantum simulations in quantum optical systems, in particular using cold trapped ions._ __ _Since 2001 he is a director of the Max-Planck-Institute for Quantum Optics in Garching, where he heads the[Theory Division](http://www2.mpq.mpg.de/Theorygroup/CIRAC/wiki/index.php/Theory_Division.html). For his research he has received many awards, among them in 2006 the Prince- of-Asturias-Prize, in 2013 the Wolff-Prize, and in 2018 the Max-Planck-Medal. _ [Prof. Cirac's web page](http://www2.mpq.mpg.de/Theorygroup/CIRAC/wiki/index.php/Prof._Dr._J.Ignacio_Cirac.html) [Wikipedia article](https://en.wikipedia.org/wiki/Juan_Ignacio_Cirac_Sasturain)
