Research
My doctoral thesis project focuses on networks of interacting quantum harmonic oscillators and in particular, on them as environments for an open quantum system, their probing via the open system, their transport properties, and their experimental implementation. I consider exact Gaussian dynamics of such networks. I am also interested in the application of graph and network theory in quantum mechanics in general. During my post-doctoral work I have also acquainted myself with reservoir computing, a form of unconventional computing suitable for implementation with physical systems, including quantum systems.
