Quantum Information using Nonlinear Graphene Plasmonics
Prof. Dr. Lee Rozema
Universidade de Viena
Abstract:
Although linear optical quantum technologies are one of the more promising routes to achieve feasible quantum technologies, in part due to the robustness and mobility of single photons, the creation of a two-qubit logic gate remains a challenge. In this talk, I will review our theoretical proposal to implement a universal quantum Zeno “square-root-of-swap” gate by encoding qubits in graphene surface plasmons. This gate does not require any cryogenic or vacuum technology, and has a footprint of a few hundred nanometers, suggesting that graphene plasmonics offers a new route towards scalable quantum technologies. I will first focus on the physics behind the Zeno gate, and then introduce the promising platform of nonlinear graphene plasmonics, showing how it could be used for quantum computing. Finally, I will present our recent experimental work demonstrating plasmon-mediated optical nonlinearities: a first step towards our long-term goal of single-photon level nonlinearities.

THE PHYSICS GRADUATE PROGRAM invites everyone to the seminar:
RAMSES II – RAMan Search for Extragalactic Symbiotic Stars
PhD. Denise R. Gonçalves
Observatório do Valongo – UFRJ (Brazil)
Abstract:
Abstract: Symbiotics are binary systems of evolved stars that show the most energetic stellar explosions after supernovae. Constituting probable channels to Type Ia SNe, they are important to understand the relation between the SN rate in a galaxy and the number of symbiotic systems at present-time. Therefore, it is very relevant to make a census of symbiotic systems in nearby galaxies. Such a census was never carried out in dwarf galaxies. In the Galaxy many symbiotic systems possess the O VI Raman scattering line at 6830A. This line allowed the discovery of a few extragalactic symbiotic systems recently, in NGC 6822, NGC 185 and NGC 205, among others. Our ongoing RAMSES II project is aimed at searching for symbiotics in the nearby dwarf galaxies, via deep narrow-band imaging that allows to detect the O VI Raman scattered feature. This detection per se implies the existence of symbiotic systems. As a follow up of this first step, we will use optical plus IR spectroscopy to completely characterize the systems, in order to better link them with the scenario of SNe Ia progenitors. In this talk I will describe the RAMSES II project and discuss its first results.
