12 Plasmon-assisted transmission of entangled photons E. Altewischer el al, 2002 Application work Plasmon-assisted transmission of entangled photons, E. Altewischer, M. P. van Exter & J. P. Woerdman, NATURE |VOL 418 | 304| 2002 | Aim to: Investigate the effects of nanostructured metal on entangled photons. Results: Such arrays convert photons into surface-plasmon —optically excited compressive charge density waves — which tunnel through the holes before reradiating as photons. Explanation: Conversion between photons and plasmons, quantum feature of SPP
