Quantum Accelerator-Efficient Fast Photonic Integrated Circuits for Photonic Quantum Computing
Abstract
Photonic integrated circuits—known as PICs—will be essential for realising photonic quantum computing, and in particular quantum neural nets, which utilize quantum effects to model complex data sets. Current PICs most often interface light in and out of the chip using edge coupling, which severely limits chip geometry as well as adding complication to fabrication. This project will develop efficient out-of-plane couplers and small-footprint waveguide crossings realising PICs that are easier to manufacture and have higher circuit density. We will use solid-state single photon sources, and manufacture our PICs in lithium niobate as it is orders-of-magnitude less lossy, and couples more efficiently, than the current industry standard of silicon-on-insulator. We will benchmark the new PIC architecture by using it to realise an event-ready entanglement circuit, quantifying its logical and circuit performance via tomography. Our new architecture lowers entry costs for PIC development, and we will ensure widespread adoption by disseminating to the community the full details of our designs and fabrication methodologies.
