Quantum Information Processing with 1010 electrons?- A short review of surface plasmon physics, recent experiments and proposals - René Stock

Surface plasmon polaritons are optically excited, macroscopic charge-density oscillations involving 1010 electrons at the surface of conducting matter. Recent entanglement preserving experiments have shown evidence of the quantumness of surface plasmons, despite the macroscopic nature of these surface excitations. The goal of this presentation is to give a short overview over the 50-year-old field of surface plasmon physics and to evaluate the usefulness of surface plasmons for quantum information processing implementations.
