Hi guys. I'm studying an article on the measurements of entanglement in a pure bipartite state.(adsbygoogle = window.adsbygoogle || []).push({});

I don't understand the definition of the Schmidt rank. It is equal to the rank of the reduced density matrix, isn't it?

Is the Schmidt rank continuous and/or additive? I have no found on the net any articles or information about this.

Could you help me?

Thanks in advance.
