I am organizing a week-long workshop in Toulouse, on topics of optimization problems in quantum information theory. Besides the usual research talks, there will be lectures by Aram Harrow, Jean Bernard Lasserre and Mihai Putinar on the topics of the workshop: linear matrix inequalities, semidefinite programming, and quantum information theory. We have still some free slots for talks, so contact me if you're interested.

RT @enclanglement Please support @fsfe's call for #publiccode: software created using taxpayers' money should be made publicly available. If it is public money, it should be public code as well! publiccode.eu
