The goal of this workshop is to establish the state of the art in quantum state/process estimation. Broadly known as "tomography", quantum estimation techniques are increasingly important to quantum information science. Despite their relevance, these tools are far from standardized. There is no clear consensus on a variety of issues, e.g.:

• When tomography is needed (when are there are better alternatives?),
• How to crunch the measurement data (linear inversion? maximum likelihood? Bayesian methods?),
• How the final estimate -- and its error bars -- should be interpreted,
• How to best gather data, and quantify uncertainty,
• How to tackle large systems.

The workshop will gather together the experts -- experimentalists, theorists, mathematicians, and statisticians -- in a stimulating environment, and encourage them to identify and solve the field's outstanding problems.
