The quantum theory of information investigates the possibilities that arise when information is encoded, stored, transformed, transmitted or decoded by means of physical devices in which quantum laws are clearly manifested. The correlations between the various degrees of freedom of these devices have been shown to offer the opportunity to design information management methodologies that can be much more efficient than any classical analog. Light can be used as a vehicle to carry out quantum information protocols through its interaction with matter. IFUNAM works on theoretical and experimental aspects for the implementation of useful devices in quantum information.
Among other research topics, the design of quantum information protocols, the detailed description of nonlinear quantum effects in crystalline media and atomic gases, the behavior of open quantum systems, the theoretical and experimental analysis of the four wave mixing in atomic gases, the study of the control of optical correlations by means of feedback and the engineering of the photons coupling with Rydberg atoms in cavities stand out.
