PhD Topic:
My research has as a main goal the production of a multi Quantum Pulse Gate (mQPG) in Thin Film Litium Niobate (TFLN) chip by using microcombs-inspired technology. mQPG are devices that facilitate high-performance quantum measurements of pulsed signal states onto several quantum-optimal measurement mode. However, the performance of these measurements is limited by achievable bandwidths and device scalability. In particular, bandwidths are limited by sample length and fabrication tolerances, whereas scalability is limited by the fabrication process. Currently, I am designing a mQPG which include microresonator technology to overcome limitations over bandwidth and using TFLN as material to guaranty scalability. When operated in the classical regime that is, at light levels that facilitate output detection with photodiodes, the device implements super-resolved frequency and time measurements in a single-shot configuration. When operated at the single-photon level, the device is naturally compatible with genuine quantum light and additional benefits in the form of entanglement will be investigated.
