Research Fellowship in "Development of a full monolithic quantum simulator on the silicon photonics platform"

The activity aims to develop an electronically programmable integrated photonic circuit capable to implement different quantum simulation protocols. The architecture foresees the monolithic integration of photon pair sources, pump rejection filters, reconfigurable quantum gates and single photon detectors. It is built on the silicon oxynitride platform and works at near infrared wavelengths (800 nm). The post-doc will be involved in the design of the photonic circuitry, from the single component level to more complex networks. The post-doc activities cover also the experimental test of their performance, which include the assessment of the main photon source metrics, the validation of the component loss and of their spectral response, the evaluation of the pump filter’s rejection and the determination of the gates fidelity. The post-doc task also includes the mapping of quantum algorithms into photonic circuits and the analysis of their outputs.

The overall research objective is to develop a stand-alone electronic-photonic unit that is capable to run few-qubit simulation algorithms to tackle quantum chemistry problems.
