Abstract

Integrated photonics is providing a compelling route for quantum limited and quantum enhanced technologies, including computing communications and optical sensing. This is because chip-scale integrated photonics can offer miniaturization as well as possible scalability in manufacture. Here we will discuss recent results in developing integrated homodyne detection integrated in silicon photonics. We discuss its combination with integrated electronics to demonstrate high bandwidth performance and its use to measure squeezed light over a broad bandwidth, out to 9GHz. This demonstrates a performance enhancement that is relevant to quantum technology and is due to miniaturization. We will discuss possible applications of of integrated quantum noise listed homodyne detection, including a strategy to perform quantum limited absorption estimation using integrated photonics and coherent states.
