...a bit of background...
My research interests are quite broad, and reflect a path that led me from computer science to theoretical aspects of quantum physics. At the early stages of my scientific training I got involved with a bit of research on Quantum Walks: beside being interesting per se, quantum walks provide a very gentle mean to convert a classical computer scientist into a quantum one, whatever the two categories mean. Indeed, quantum walks are a simple setup to model fundamental phenomena, such as transport of energy and/or information. While walking in quantum realm, one comes very soon to terms with the fact that quantum objects are subjected to noise and decoherence; and one learns, often the hard way, that states are seldom vectors but much uglier matrices, and that the real-life evolution of a quantum states obeys master equations more often than nice, clean and simple Schrödinger equations. This represented the second "phase transition" of my research path: I got attracted by the "open quantum systems side" (which intentionally sounds a but as the Dark Side, because it is close to it!). Beside providing an immense playground for the computer simulation of quantum systems (simulating open quantum systems is typically much, much harder than simulating closed ones of the same size), open quantum systems are ubiqitous, and are the key to understand the transition from the quantum to the every-day-life experience world.
Among the topics I dealth with, and hopefully gave an ε-contribution to, there are: Interacting quantum walks (a.k.a. Feynman quantum computer), Quantum transport, Quantum biology, Characterization of open quantum systems, Simulation of open quantum system (with structured environments), Quantum metrology, Efficient simulation of complex systems via GPU-computing, Tensor Networks (DMRG).
