Project Description

Emerging optical technologies such as planar metasurfaces and integrated quantum photonics promise to bring revolutionary advances to fundamental science of light and light matter interactions as well as to enable an entirely new generation of compact, efficient, and multifunctional devices for breakthrough applications in information processing and storage, computation, secure communication, nanometer-scale imaging, sensing and future quantum IT. Artificially engineered, ultra-thin photonic metasurfaces have already enabled unprecedented abilities to process and measure quantum information. Together with the emerging single photon sources, metasurfaces can enable quantum RAM concepts (qRAM) where multiple degrees of freedom of single photons are used in order to emulate the address, data and qRAM qudits. The single photons will interact with a sequence of metasurfaces performing the entangling operations between the different degrees of freedom. At the end of their trajectory the photons will be subjected to quantum tomography measurements to determine their full quantum state in all the degrees of freedom involved. This tomography will serve as a proof of a quantum evolution analogous to a real qRAM. This project will be a pioneering effort featuring an efficient interface between a classical and a quantum data world.
