Interactions of quantum light with nanoparticles
In this project we used entangled photons to illuminate a small nanoaperture drilled on a film of gold. Even though the round hole was smaller than the wavelength, we measured that there is a different transmission of states with different quantum phases. In particular, some states would be transmitted and their entanglement preserved, while for others, the entanglemetn would be completely destroyed. The key ingredient in this project was to engineer the modes of light to match the symmetries of the structure.
