DESCRIPTION:Co-authors: Richard Kng (University of Freiburg)\, Felix Krahm
 er (University of Goettingen) \n\nOptical sensors pick up the intensity of
  light fields\, but are insensitive to phase. It is\, however\, conceivabl
 e that an "overcomplete" set of intensity measurements may allow one to re
 construct the complete state of the light field emanating from a given obj
 ect. In the past two years\, stable algorithms with rigorous performance g
 uarantees for this "phase recovery problem" have been developed. They are 
 ultimately based on low-rank matrix recovery algorithms whose technical an
 alysis has benefited from methods originating in quantum information. I wi
 ll review these developments and present new results towards the de-random
 ization of phase estimation protocols.\n\nRelated Links: http://www.qc.uni
