    Tesis
    Acceso abierto
    According to recent estimates, 10^18 bytes of data are generated on a daily basis around the globe. Our information society urges for radical solutions to treat such data deluge. By exploiting fundamental key elements of ...
  • New systems for quantum nonlinear optics 

    Manzoni, Marco Tommaso (Universitat Politècnica de Catalunya, 2017-10-19)
    Tesis
    Acceso abierto
    Photons travelling through free space do not interact with each other. This characteristic makes them perfect candidates to carry quantum information over long distances. On the other hand, processing the information they ...
  • Quantum memory protocols for photonic solid-state devices
