Constraints on the mixing of states on bipartite quantum systems
Hao Chen
We give necessary conditions for the mixing problem in bipartite case, which are independent of eigenvalues and based on algebraic-geometric invariants of the bipartite states. One…

Algebraic-geometric separability criterion and low rank mixed state entanglement
Hao Chen
We first propose a new separability criterion based on algebraic-geometric invariants of bipartite mixed states introduced in [1], then prove that for all low ranks r <m+n-2, gener…
