Prize and the Science Research Prize of the Mexican Academy of Sciences, both in 2006. In 2021, he was awarded the Marcos Moshinsky Medal by UNAM's Instituto de Física. He served as President of the Division of Quantum Information of the Mexican Physical Society from 2011 to 2013. From 1996 to 2015, he was a Regular Associate of the International Centre for Theoretical Physics. He has published important works on the generation of non-classical states of the quantized electromagnetic field and in trapped ions. He has also studied analogies between classical and quantum systems in waveguide arrays and with coworkers has experimentally shown how to perform the discrete Fourier transform (DFT) in these types of systems. Using this he has shown that precisely the DFT of a number operator in an s-dimensional

corresponds to the best definition of a phase operator in quantum optics: the Pegg and Barnett phase operator. In Optics he has shown that the Bohm potential can be used to explain the Gouy phase. He has also shown that a GRIN medium, when studied beyond the paraxial approximation, generates an analogy with a quantum Kerr medium. By being able to generate non-classical states such as Schrödinger's cats (superposition of coherent states), the separation of a Gaussian beam can be generated in this way without the use of beam splitters. He has written several books involving Quantum Optics,
