12:00 – 1:00 p.m.

Phase retrieval is important to a variety of fields, ranging from astronomy to x-ray crystallography and biomedical imaging. It is also a beautiful example of computational optics, in which both physical measurement and numerical processing are required to achieve the final result, e.g. reconstruction of phase information from intensity-only measurements. Here, we will discuss how spatial nonlinearity and quantum entanglement can improve upon classical (linear) phase algorithms. In particular, we will show how wave mixing and correlations lead to simultaneous improvement of resolution and contrast, enhanced sensitivity with reduced noise, the removal of ambiguous solutions, and criteria for stopping iterations and optimizing the unknown phase.
