Title

On-chip generation and processing of ultrafast time-entangled photonic qudits for quantum communications

Abstract
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.
