Integrated Quantum Photonics has the potential of realizing Complex Quantum Circuits for performing Quantum Light Generation, Manipulation and Detection in small foot-print and at high efficiencies.

As part of the QuEST Project: Sources for Quantum Information Processing (Q-39), we are working on the Integrated Photonic Building-Blocks such as Quantum Light Sources and Manipulation Optical Devices to be used in Quantum Communication and Sensing.
