Quantum technology – Qubits and quantum emitters – Magnetic quantum emitters


Mathieu Mivelle

It is generally considered that the interactions between light and matter are mediated only by the electric field component of light, neglecting the other major component of electromagnetic waves. This is particularly relevant in quantum optics where the electric field component of light is coupled to the electric dipole of a quantum system. However, the electric and magnetic optical fields carry the same amount of energy, which leads to the conclusion that half of the interactions between light and matter are neither studied nor exploited.
The objective of our research is to develop innovative optical nano-antennas to adapt the interactions between “magnetic light” and matter at the nanoscale.
We theoretically design, physically nanostructure and experimentally characterize photonic antennas that create pure, strong and confined magnetic light hotspots and deterministically place them in the vicinity of quantum emitters with magnetic dipolar transitions, thereby significantly enhancing the interactions between “magnetic light” and matter.
This research program represents a new paradigm in the fundamental understanding of light-matter interactions and will open new horizons in research areas as diverse as nanotechnology, sensing, biology, quantum and molecular chiral optics, nonlinear and nanoscale optics, spintronics and metamaterials, among others.
