The Permanent Rank of a Matrix (Part Three) Note on the Additive Basis Conjecture
Yang Yu
We show that in a vector space over Z_3, the union of any four linear bases is an additive basis, thus proving the Additive Basis Conjecture for Z_3, and providing an alternative p…
The positive partial transpose conjecture for n=3
Lin Chen, Yu Yang, Waishing Tang
We present the PPT square conjecture introduced by M. Christandl. We prove the conjecture in the case as a consequence of the fact that two-qutrit PPT states have Schmidt at…
Schmidt number of bipartite and multipartite states under local projections
Lin Chen, Yu Yang, Wai-shing Tang
The Schmidt number is a fundamental parameter characterizing the properties of quantum states, and the local projections are a fundamental operation in quantum physics. We investig…
All 2-positive linear maps from M3 to M3 are decomposable
Yu Yang, Denny H. Leung, Waishing Tang
Following an idea of Choi, we obtain a decomposition theorem for k-positive linear maps from Mm to Mn, where 2<=k<min{m,n}. As a consequence, we give an affirmative answer to Kye's…
