Quantum Nanophotonics Laboratory Research groups

The research program of the “Quantum Nanophotonics Laboratory” group aims at contributing to the development of hybrid quantum devices based on the interaction of light and matter at the nanoscale. It is a team of scientists endeavoruing to unveil the physics of the interactions of quantum light and matter at the nanoscale. It experiments with exotic states of light, such as single photon states, entangled photons or squeezed states of light, and force them to interact with very small structures. This allows for the design of more precise quantum enhanced sensors and improve information processing.Research topics:

  • Interactions of quantum light with nanoparticles. Entangled photons are used to illuminate a small nano-aperture drilled on a film of gold. The key ingredient is to engineer the modes of light to match the symmetries of the structure.
  • Controlling the scattering of nanoparticles with light modes. Light scattering from small particles is what gives the blue colour to the sky or the white opacity of milk. The main theory was developed around 100 years ago, but it did not taken into account the amazing progress in the control of light modes, combining sources of light with spatial light modulators and polarization controllers. Controlling the modes of light, the scattering from individual small particles can be controlled, making possible to manipulate light at the nanoscale.
