Converting LaTeX to word processor formats is the holy grail of document conversion. Perhaps we are getting closer to a viable solution.

## Quantum process tomography and machine learning

The optimal estimation of a group of unitary transforms allows for learning an unknown function: this is similar to regression in classical machine learning.
