Overview

Theoretical exploration demonstrates dynamic manipulation of quantum emission in high-temperature environments, suggesting new scalable quantum technologies.

Key Points

  • This investigation aims to achieve dynamic and broadband control of superradiance and subradiance in quantum emitters using near-field photonics.
  • Theoretical investigation combining near-field photonics with time-varying media.
  • Exploitation of plasmonically coupled silicon carbide color centers as quantum emitters.
  • Use of hybrid plasmonic waveguide for nanoscale heating and modulation.
  • Employment of transparent conducting oxides for refractive index modulation on ultrafast timescales.
  • Demonstrated effective operation of the approach at practical temperatures (tens of Kelvin).
  • Achieved dynamic control over the quantum emission states, facilitating superradiance and subradiance.
  • Amplified light localization around quantum emitters, extending periods of super- or subradiance compared to static conditions.
