Theoretical Investigation of Surface Phonon Polariton-Based Quantum Photonic Circuits


The primary goal of the PhonologiQ research program herein described is to produce a simple and clear set of analytical expressions that detail the dependence of the efficiency of a surface phonon polariton-based integrated quantum photonic circuit on the material and geometric parameters of its nanoscopic components. This research will focus on three primary areas of novelty: 1) incorporating radiation into models of interactions between phononic waveguides and quantum emitters and antennae, 2) describing the effects of material nonlocality and anisotropy on the fundamental performance limits of the circuit, and 3) investigating novel hybridization-mediated pathways through which the efficiency of nonlinear circuit elements like switches or light sources can be enhanced without losing energy to radiation. Upon successful completion of the program, the results will be a useful roadmap by which experimental researchers working to realize the next generation of quantum photonic information processing systems can formulate concrete design criteria. The planned speedup to Europe's development of cutting edge computing technologies falls within the stated goals of the Horizon 2021-2022 Work Program to strengthen the R&I capacity, output, and transfer within and between European research institutions.
