Abstract : Highlights of our research program include the demonstration of Hong-Ou-Mandel interference of surface plasmon polaritons, proving directly the bosonic nature of surface plasmons. This constitutes a first step towards active nanoscale quantum information processing devices based on surface plasmon polaritons. We demonstrate that despite the high losses in surface plasmon waveguides, which we investigated using single-photon to single-plasmon conversion, single surface plasmon polaritons can interfere quantum mechanically and show the characteristic bunching at the output ports of a four-terminal device. The second highlight is the publication of a roadmap for the field of quantum plasmonics, published in Nature Physics with cover page of the journal. In total this project has thus far resulted in six journal articles. We are currently writing up an additional work, on direct quantum tomography on state entanglement in quantum interferometers, which could form the basics of quantum sensing.
