The extraordinary progress of nanofabrication techniques has allowed the accurate control of the morphology of nanostructures at the nanometer and subnanometer scale allowing the realization of plasmonic antennas with atomistic separation distances. The necessity to handle gaps approaching the Angstrom scale, has, thus, required a quantum-mechanical approach to the study of the plasmonic excitations. This work aims at shedding light on the charge transfer role in plasmonic excitations involving sub-nanometer separation distances among the considered metallic clusters by taking advantage from the subsystem formulation of Time-Dependent Density Functional Theory.

Monolithic semiconductor light sources for quantum photonic integration on Si

Abhiroop Chellu, Joonas Hilska, Jussi-Pekka Penttinen, Teemu Valtteri Hakkarainen

Optoelectronics Research Centre, Physics Unit, Tampere University, Finland

Semiconductor quantum dots (QDs) represent the state-of-the-art of deterministic sources of single and entangled photons for quantum photonics. However, so far there has been no feasible technology for scalable integration of the best QD emitters with the Si photonics platform. Here, we present a new, highly uniform semiconductor quantum system based on GaSb QDs formed in AlGaSb by filling droplet-etched nanoholes. These QDs provide narrow-linewidth excitonic emission at telecom wavelengths and allow direct epitaxial integration with the Si photonics platform.

Practical quantum communication and processing

Fabio Bovino

Sapienza University of Rome, Italy

Multirail Architecture encode the whole state space in a complex optical circuit, and it provides a novel class of small or intermediate-scale processors that allow “quantum supremacy” and practical implementation of quantum communication and authentication
