Quantum Photonic Integrated Circuits

The development of scalable optical technologies for quantum cryptography, communications, and computing requires reducing existing table-top experiments to fully integrated chip-scale photonic circuits. We utilize several approaches for efficient chip-scale quantum photonics, including AlGaAs, InGaP, silicon nitride, and their heterogeneous integration. Through wafer-scale fab in UCSB's cleanroom, we integrate ultra-bright entangled-pair sources, squeezers, and quantum frequency combs with ultra-low-loss photonic circuits, passive and active components, and superconducting nanowire single-photon detectors. By monolithically integrating all quantum photonic components onto a single platform, we significantly reduce the size, weight, power, and cost (SWaP-C) while simultaneously enhancing the power and phase stability, scalability, and manufacturability. 

Key application areas we develop our photonic hardware for include quantum information processing, communications, and sensing.
