On-Chip Generation and Processing of Ultrafast Time-Entangled Photonic Qudits for Quantum Communications

We present a photonic platform for the generation and processing of picosecond-spaced time entangled qudits, based on on-chip interferometers and a spiral waveguide. We utilize these qudits to implement quantum communications over standard optical fibers.
