Quantum Information using Nonlinear Graphene Plasmonics

Prof. Dr. Lee Rozema

Universidade de Viena


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.
