Nonlinear integrated photonics for quantum communications and computing
Galan Moody
Abstract
With recent and rapid progress, compound semiconductor on insulator (CSOI) photonics is transforming quantum technologies by providing new functionalities and capabilities not possible with traditional, silicon-based photonics. In this talk, I will discuss how we can leverage the strong nonlinearities and low propagation loss of AlGaAs-on-insulator photonics for quantum computing and communications. I will present recent results on entangled-pair and squeezed-light generation, on-chip frequency bin processors based on integrated modulators and pulse shapers, and architectures for high-dimensional graph-state generation for distributing entanglement across quantum networks.
