Hipólito Gómez is a researcher of atlanTTic (COM group) and recently beneficiary of one of the post-doctoral grants of the Xunta. The next two years will be spent in a stay at the University of Toronto, where he will continue to deepen in his field of work, quantum cryptography. We had a brief interview in which he talked to us in more detail about his stay.

What is your field of work?

My field of work during the realization of the thesis at the University of Vigo was mainly Computational Electromagnetism. My work on the thesis was the preparation of computer programs to simulate complex emitting devices and electromagnetic wave receivers at different frequencies. After completing the thesis in December 2015, I was hired during a year as a postdoctoral researcher at Northeastern University in Boston, where I continued with the same research topic that I had been doing in Vigo as a doctoral student.

What is your work in Boston about and what are the applications?

The research I carried out in Computational Electromagnetism was interesting and I had the opportunity to participate in Boston within an important interdisciplinary research group. We satisfactorily use concepts in my field of work in numerous applications. For example, in the design of nano-robots for obtaining images of cell membranes, which has earned us even a prestigious award at the EuCAP’16 congress, the most important annual event in Europe and one of the most important in the world on general applications of Radiocommunication and electromagnetic engineering. One news about this award has been published in the DUVI UVIGO newspaper: https://duvi.uvigo.es/index.php?option=com_content&task=view&id=11586 .

What university will your stay in and why did you choose that university?

I was granted a postdoutoral grant from the Xunta to investigate for 2 years at the University of Toronto. I must say that getting this help has been possible thanks to the reasonable technical quality of my work done in recent years, and therefore I am very grateful to my two thesis directors, Prof. Oscar Rubiños and Prof. José Ángel Martínez. For post-doctoral stay of 2 years, I chose the research group from Prof. Hoi-Kwong Lo, from the University of Toronto, since it is a global reference group in the field of quantum information, both theoretical and experimental, and quantum communications in particular. In addition, this group owns and manages two internationally renowned experimental laboratories for the practical analysis of quantum communication protocols. It should be added that the University of Toronto is a public university of Canada that in the last Ranking of Shanghai appears in position 25 at the international level and in position 23 for the specific area of ​​engineering, even surpassing in this section to many American private universities of “Ivy League.” Other international rankings collect similar results.

What will be your research lines in Toronto?

My work in Toronto will be part of Quantum Cryptography research. Emphasize that Quantum Cryptography is an area of ​​knowledge aimed at guaranteeing a data transmission in a totally safe way. These are systems that can not be broken in any way, not even with unlimited computational power. Therefore, in today’s world, companies, institutions and governments work to provide secure and reliable networks based on this type of protocol. Currently, such commercial systems already exist in different countries, such as the USA, Japan, China and Switzerland. My work will focus, above all, on proposing different modifications in existing Quantum Key Distribution protocols (QKD: Quantum Key Distribution), in order to achieve higher rates for key generation and higher transmission distances, among other advantages.
