Quantum Mechanics: Axiomatics of Measurements and connections with Computing and Information Retrieval

Generation, manipulation, and tomographic analysis of quantum states of light

aula DOTTORATO - LUNEDì 19 FEBBRAIO ore 14.00
  MARCO BELLINI, Istituto Nazionale di Ottica Applicata, Florence - Italy

Marco Bellini is a Senior Researcher at the Istituto Nazionale di Ottica Applicata - CNR, in Florence. He received his PhD in Physics in 1995 from the University of Florence. His initial research field involved high-resolution spectroscopic investigations of atoms and molecules in the Far Infrared but has later moved to the generation and applications of ultrashort pulses in the Extreme Ultraviolet by means of high-order laser harmonics. His main research activity today is in the field of experimental Quantum Optics where he is currently interested in the generation and tomographic analysis of novel quantum states of light. He is co-author of more than 75 papers in top international scientific journals.

  I will present some of the recent experiments performed in Florence and concerning the generation and measurement of quantum states of light. In particular, I will focus on the remote coherent delocalization of a single photon onto distinct temporal modes and on the time-domain homodyne detection of the resulting field. The tomographic reconstruction of the density matrix and of the Wigner function of the state has allowed us to experimentally quantify its entanglement and to test a novel tomographic approach to the violation of Bell’s inequalities.
