Welcome to Wikipedia. Everyone is welcome to contribute to the encyclopedia, but when you add or change content, as you did to the article Paweł Horodecki, please cite a reliable source for the content of your edit. This helps maintain our policy of verifiability. See Wikipedia:Citing sources for how to cite sources, and the welcome page to learn more about contributing to this encyclopedia. Thank you. You must add references. I have added one (to avoid it being deleted); it needs more. Chzz ► 19:56, 24 February 2011 (UTC)
