Advancements in Integrated Quantum Circuits: Photon Conversion and Entanglement Generation

Synopsis

Utilizing nonlinearity as a quantum resource not only enables the creation of entanglement, a fundamental aspect of quantum mechanics, but also plays a vital role in advancing quantum computing capabilities. In this presentation, I will explain recent advancements made by our team in harnessing nonlinear processes to generate entanglement and squeezing. The discussion includes the utilization of integrated optical and microwave circuits to develop robust nonclassical sources as well as for microwave-to-optical transduction. The first part of the talk is devoted to the use of nanomechanical resonators for photon conversion and transduction, while the second part explores the application of superconducting kinetic inductance thin films for signal amplification and squeezing in the microwave domain.
