Ernesto F. Galvão

I am a postdoctoral research fellow at the Perimeter Institute for Theoretical Physics, in Waterloo, Canada. Prior to coming to Perimeter in the fall of 2002 I got my PhD from the University of Oxford (they actually call it a DPhil there), where I was part of Wolfson College. Before that I got a Master's degree in quantum optics from Universidade Federal do Rio de Janeiro and an undergraduate degree in physics at Pontifícia Universidade Católica do Rio de Janeiro. As you are probably guessing by now, I’m a Brazilian from Rio de Janeiro.


I work in the areas of quantum information and foundations of quantum mechanics. More specifically, I like to establish connections between these two fields. Among other things, I’ve done work on discrete Wigner functions, non-locality, contextuality and quantum communication complexity. I am also interested in investigating the experimental feasibility of small-scale quantum information processing applications, such as quantum random access codes, quantum communication complexity protocols, etc.

The first chapters of my Ph.D. thesis include an introduction to some issues on foundations of quantum mechanics and quantum information. A more complete list of my scientific publications can be found here.

Other stuff
