Quantum photon manipulation and measurement with ultra-thin metasurfaces
Abstract
Manipulation and measurement of quantum photon states are essential capabilities for the realization of quantum networks, including fiber-based and free-space communications. Traditionally, this is performed through multiple stages of photon shaping and interference, implemented with bulk optical components or extended waveguides. However, such approaches require precise alignment, being sensitive to the environmental instabilities, such as vibrations and temperature variations. We have developed a new fundamental approach based on ultra-thin all-dielectric metasurfaces, where a single nano-layer encodes multiple parallel quantum state transformations. This platform achieves the ultimate miniaturization and stability combined with high accuracy and robustness, while overcoming the limitations of lengthy sequential implementations. In particular, we suggested a new approach to binary metasurface design, which can simultaneously act as polarization wave-plates and perform polarization-dependent filtering, the latter being a topic of recent interest in quantum networking.
