Title:  Finding Knowledge: Adventures Using the Shape of Light

Abstract:
The transverse shape of light has emerged in recent years as a promising platform for encoding quantum information, for the multiple levels that it affords and the ease with which shape can be controlled. To demonstrate, I will discuss high-dimensional quantum state tomography.  
We used a tomographic technique inspired by machine learning to track a quantum state as the state changes. The method is computationally efficient and also robust—it converges to a good estimate even in the presence of strong noise.   Developing techniques like this is especially important for systems that are of high dimensionality, where making tomographically complete measurements become impractical.
