QUAntum nanophotonics in Rolled-Up Metamaterials

Periodic Reporting for period 1 - aQUARiUM (QUAntum nanophotonics in Rolled-Up Metamaterials)

Reporting period: 2019-01-01 to 2020-06-30

The development of photonic technologies has gained a prominent position in our daily life from communication to medicine. In order to harness and process light in the single photon level requires the implementation of quantum physics to the photonics applications. However, the interaction of light with single quantum systems under ambient conditions is typically very weak and difficult to control. Furthermore, there are quantum phenomena occurring in the matter at nanometer length scales that are currently not well understood. These deficiencies have a direct and severe impact on creating a bridge between quantum physics and photonic device technologies.
Project aQUARiUM precisely addresses the issue of controlling and enhancing the interaction between few photons and rolled-up nanostructures with ability to be deployed in practical applications.
The results of the project will have significant impact on quantum photonic device technologies as it aims to provide a wholly new photonic platform applicable across a diverse range of areas. This project addresses some of the most promising concepts and applications of quantum nanophotonics, which opens up new ways and possibilities to revolutionize the technology.
During the first reporting period of the project, we designed rolled-up epsilon (permittivity)-near-zero (ENZ) metamaterials using numerical and analytical platforms. We have achieved the first milestone defined in the research description. Additionally, we defined quantum emitters as two-level systems and obtained the solution of their interaction with incident photons in a rolled-up ENZ medium (Milestone 2).
We have also progressed in the fabrication of the rolled-up nanotubes. We have optimized 3 different methods to obtain the rolled-up structures in different diameters and material composition. These optimized methods provide us to fabricate the rolled-up metamaterials for different applications in the next steps of the project. Initially, we obtained planer ENZ metamaterials and demonstrated that these metamaterials provide exciting properties to control the emitter properties as well as they can be dynamically tunable optically.
Finally, we have installed and obtained the initial test results of the experimental setups which will be used for the characterization of the structures especially for quantum applications such as quantum communication and computation.
The results of this project will create quantum networks, where single emitters coherently connected for quantum information processing and new developments of quantum communication. Moreover, the results may lead to the novel light sources with low-threshold nanolasing or electrically controlled single photon sources are required for integrated photonic circuits. These applications are highly relevant for modern photonic technologies.
By the end of the project, the project results will go beyond the state of the art in the manipulation of the interaction of the emitters. This will result in a novel light source especially for quantum applications by the end of the project.
