Research Interests

  • Quantum information (Cryptography, Entanglement, Topological Quantum Computation, Quantum channels and maps),
  • Quantum and statistical field theory (Exactly solved models, matrix product states in spin systems and in quantum field theory)

 

Research Plan

For my PhD project I worked on Quantum Groups, a topic which I liked very much for its pure and beautiful mathematics, and its many interconnections to various fields of theoretical physics of the time (the 90's). When I left quantum groups for no reason, I had a sense of nostalgia for many years, and actually I never had that kind of internal satisfaction with any other field. After graduation I continued to work in this area for a number of years with sporadic interests in other fields of mathematical physics, mainly integrable models, and non-equilibrium many body systems in one dimensions. I also worked a little bit with one of my PhD students, on small world networks but quickly left it, since it was far from my interests. It is now a few years that I have settled down in quantum computation and quantum information. At first I worked on thermal entanglement of many body systems and then on matrix product formalism. Now I am studying topological quantum computation.
