Sophie Berthelette

I am a postdoctoral researcher at the Università della Svizzera italiana (USI) in the Cryptography and Quantum Information (CQI) group. My research sits at the intersection of physics and information theory, focusing on the role of computation in understanding physical concepts. I specialize in applying algorithmic information theory to the study of thermodynamics and quantum correlations.

I obtained my PhD in physics from the University of Montreal under the supervision of Gilles Brassard. My doctoral work investigates a non-probabilistic approach to statistical mechanics. I also hold an MSc in physics from the same institution, where I studied quantum correlations cropping up in the magic square pseudo-telepathy game using algorithmic complexity.
