Research
I am fascinated by quantum information, machine learning, networks and primarily, the interface of these three. I’m particularly interested in using neural networks for understanding quantum phenomena on networks better.
Currently, I work as an SNSF Postdoc.Mobility fellow in Antonio Acín’s group (QIT group) at ICFO, Castelldefels (Barcelona).
